User Generated. Lab 1 - Electric Field and Electric Potential Introduction Physicists use the concept of a field to explain the interaction of particles or bodies through space, i.e., the "action-at-a-distance" force between two bodies that are not in physical contact.The earth modifies the surrounding space such that any body with mass, such as the moon, is attracted to it. it will stay on it. If the sticky side of both the tape. Observe and record what happens to the balls. vvjut. The magnitude of the electrostatic force between two-point charges ql and q2 is given by Coulomb's law. Bring it near your lab partner's knuckle. USW00094728 If the angle \(\phi\) is small, then \(\tan\phi = \sin\phi\), and \(d\) is proportional to \(F\). The spreadsheet. Inside a polarized Protons Distance (m) Voltage (V), Volts/Meter Electrons are being transferred from the balloon to the sweater. When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall. Measure all currents, voltages and power readings at same load settings of resistor load cart from step 5. Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. The excess amount of negative charge in his body will go through the doorknob as he touches it. Rub the second lucite rod with silk, and bring it close to the first rod. Step 2: Note down the reading on the ammeter and the voltage of the battery. Electrons will actually move along this path to the ground. With this movement have come new types of applications and rapid advances in the technologies and techniques needed to fabricate the increasingly miniature devices that are literally changing our world. The data does suggest. What happens in each case? different fabrics, such as cotton, silk and wool. Include in the discussion the vocabulary: charge transfer and electric attraction. Record the results your notes. induction, and conduction INTRODUCTION: In this activity we will use very simple objects to investigate electric charge. It is pretty easy basic calculations, Electricity, Magnetism, and Light Compare/Contrast Paper. The lab TA will provide more instruction. What is the exponent of the \(r\)-dependence of the force? Static electricity occurs whenever you have an accumulation of one type of charge. She found a charging station with a USB adaptor port. Keep the rod in position. The purpose of the mirror is to minimize parallax errors in reading the scale. The conductor has been charged without actually being touched with the charged rod, and its charge is opposite that of the rod.

For your records, you may print out your Excel file with a table and graph of your numerical observations and any other electronic files you have generated. (transfer of charge, induction, attraction, repulsion, and grounding). This is an electric field and electric potential lab. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone's screen told her the phone was successfully charging. If you use two of the same charges to move the puck, it would move twice as fast, if you use two Static electricity or Electrostatics David Case: March 6, 2015 Experiment #8 Static Electricity or Electrostatics Objective: To explore the concepts of static electricity and to discover how many types of electrical charges exist and how they interact with each other Materials: Using the values from the experiment, we found that the slope of the line is 1.51. Discussion, Results and Conclusion Conclusion This lab aimed to show the effects of electrostatic forces between different charged objects. An empty meter should appear; to start the measurement press the green 'play' button at the top of the screen. In a metal, a charge can move freely and stay on the surface. a. Neutral particles do not interact with electrical forces. 562v=0v2) Verify KCL in figure 3 circuit from hardware measurement. To experimentally investigate electrostatics, some chargedetecting or measuring device is needed. General Physics II Lab (PHYS-2021) Experiment ELEC-1: Electrostatic Charges Objective: InPartAoftoday'sexperimentyouwilldemonstratethelawofconservationofchargeaswell increases. The electric field surrounding a charged object gets weaker with distance, the object will have a stronger attractive force on its closest charges of opposite sign and a weaker repulsive force on the like charges farther away. Data section includes the provided table; observations are reasonably accurate and the conclusions regarding the charge are consistent with the observations. Other materials such as glass are insulators. If the needle falls to 0 in 15 seconds or so, as it does on some summer days, you will probably have difficulty completing the experiments, even with the help of the heat lamp. particles, on the force between them. The hanging ball should be repelled strongly. Charge sticks on an insulator, but does not move freely through it. Assist the Continuous Improvement Manager on data collection, analysis, and compilation as it relates to LEAN projects throughout . always steal electrons from things they come in contact with; others are. Static move? For this experiment, I got the negative charges from the sweater for both balloons. Question 1: When the balloon is rubbed on the sweater, what might happen?

User generated content is uploaded by users for the purposes of learning and should be used following Studypool's. This process is called charging by friction. it should be brief, start with a key word, and indicate the nature of the experiment. what happens and then repeat the demo. In the induction process of charging, a charged object is brought near to but not touching the electroscope. 4.Ask Reflect on your answer to #2, write down how your thinking has changed. Have a class discussion. AST 109 Western Nevada College The Rotation of The Sun Lab Report. They were attracted to Surrounding a charge there is an invisible electric field which gets weaker the farther away one gets from the charge. In the demo John Travoltage is basically attaining negative electrons/particles due to stepping and rubbing his foot on the carpet, once he touches the door knob that is metal he is shocked or slightly electrocuted. First, we observing what happens. This is explained by the like charges repel principle. When charge was transferred to the top, the gold leaves would become charged and repel each other. Electric field lines are typically drawn to visualize the field. This procedure is called charging by induction. If this is the case, you can try again next week. negative charges quickly left his body as he touched the doorknob as shown below. A static charge is produced because some electrons are transferred from one object to the other. I have already completed the abstract, procedure, data and collections, but I have a hard time putting everything together and for the discussion, I only talked about what electrostatic force is and how electrons protons neutrons make up all matter and how when two different objects are rubbed together, electrons are transferred from one . electrons leave the plate and enter the needle, both plate and support/needle acquire an imbalance Their electrons are bound tightly and cannot move. and conclusions sections - and possibly what could have been done (if anything . Charge the rough plastic rod with cat's fur. There were four unknown solutes A, B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. When you rub a ruler with different materials, it can cause it to gain or lose static electricity depending on its electrical conductivity. It is referred to as a "proof plane". sweater so that it is able to collect electrons, then once you place the balloon near the wall When rubbed, a piece of amber can attract small objects like tiny pieces of paper.

Fixed Distance, Changing Charge 1. force. when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's. This can happen when two non-conducting materials are rubbed together for example plastic and fur. Say Discuss with your partner what is happening when he touches the knob. Repeat the demo several times. Cross), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E. Bursten; Catherine Murphy; Patrick Woodward). investigation support or change your ideas. Make sure that they understand that this is commonly called grounding. negative charges affect the puck when displayed in the hockey University Physics - OpenStax 2016-11-04 University Physics is a three-volume collection that meets the scope and sequence requirements for two-and three-semester calculus-based physics courses. This USB port seemed to have very high amperage, meaning it charged her phone quickly. I tried to put As a result, like charges repel each Abstract: This lab focuses on Newton's second law and Coulomb's law. Use a little whipping motion at the end of the rubbing. Open phet.colorado/sims/html/balloons-and-static-electricity/latest/balloons-and- A whipping motion toward the end of the rubbing may help. i. The study of the Coulomb forces among arrangements of stationary charged particles is called electrostatics. The general conclusion is that there are two kinds of charge, which are in some way opposite. Lift off the metal plate by its insulating handle, and touch it carefully to the ball on the left sliding block. Comment in your notes. attachment_3. Step 3: Add an extra bulb into the circuit loop. What should you plot against what? Procedure When you are asked to write your observations, please do so in a clear, complete manner. A new classified U.S. Dept.

Question 4: What might happen to the charge on the man when he touches the doorknob? Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday that demonstrates the effect of electrostatic induction on a conducting container. Recharge the metal plate by placing it back on the lucite, touching the lucite, and then lifting the plate off with its insulating handle. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. different fabrics, such as cotton, silk and wool Electrons are essentially being transferred from the balloon to the sweater. You may use the stopwatch function of your wristwatch. The fundamental concept in electrostatics is electrical charge. (You may feel a slight shock.). Hit RESET to do this several times. A. Lynn University. : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Using Coulombs law, we can explore the effect of the distance, between two charged Critique the lab and describe opportunities for further / future work. The conductor has been polarized, and will now be attracted to the charged rod. B. BOOK Capacitors And Electrostatics Lab Report Conclusion PDF Book is the book you are looking for, . grounding. Consequently, Values of Thickness 2. Once a charge is placed on an insulator, it will remain at the same spot until it is neutralized . Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. To understand the response of the electroscope when a charged rod is brought near, so that the electrical charges on the rod interact with charges already present in the electroscope. This part uses the Charges and Fields simulation from PhET Interactive Simulations, Learning Goals: Students will be able to describe and draw models for common static Please write answers direct on the PDF file. 1. 3 1 m 18 V 12 V/m Both the negative and positive charges have the same pull/push strength that can affect the positively charged puck and they are different in the way they affect the puck by either pulling or pushing. Coulomb's Law describes three properties of the electrical force: The force is inversely proportional to the square of the distance between the charges, and is directed along the straight line that connects their centers. Opposite charges attract each other. Record the time it takes the electroscope needle to fall completely to 0. As shown in the demo below, the sweater is positive and the balloon attaches to the repel, and objects of opposite charges attract. Bring the lucite rod near (but not touching) the top of the electroscope, so that the electroscope is deflected. Placeq 1 andq 2 4cmapart. Volta characterized it as an inexhaustible source of charge. equal to 9 x 10 9 N 2 /C 2. Science. Aug 2021 - Dec 20215 months. Wool is a conductive material, which means it readily gives away its electrons. Electrostatics - Version 7.0 - University of Michigan-Dearborn . Say Discuss The material gaining electrons now has more electrons and becomes negative. Wool is a conductive material, which means it readily gives away its electrons. Rub the rough plastic rod with cat's fur, and bring this rod near the lucite rod in the stirrup. Examine the image with a positive and a negative charge on the playing You can ameliorate this effect somewhat by shining a heat lamp on the insulators in the apparatus. This can happen This process extends to other objects and real world applications, such as the controlling of electrical cable manufacturing and application in areas such as a television depot station, where static electricity must be managed and accounted for to avoid disruptions. several objects found around the home made of wood, glass plastic and rubber Electric charge comes in two forms: positive and negative. Does it matter which side faces which side? Once the electrons leave the plate and enter the needle, both plate and support/needle acquire an imbalance of charge. This force decreases as the distance between the charges increases. Is there any difference in the behavior of the needle compared to the results in procedure 6? ), The displacement \(d\) of the hanging ball from its equilibrium position depends on the electrical force \(F\) which repels it from the sliding ball. Repeat steps 1. As a result, like charges repel each other and unlike charges attract each other. static-electricity_en, Determine how different objects interact through the electrostatic force. If you have done everything correctly, the electroscope should have a permanent deflection. Electric fields and gravitational fields are alike in the sense that they both act upon a system and are dependent of it. Touch his finger to the door knob to show grounding. Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. What is the average distance a spark will jump? Later, other materials were found which exhibited this same behavior. then repeat the demo using the sim. Lift off the top cover and look down on the ball. contrast to the one from the negative charge? The current should be read on the 300 mA (or lower) scale. SHOW ALL CHARGES and ask the students to write observations and include drawings and Write down "attract" or "repel" according to your observations. Are you in need of an additional source of income? Record the results in your notes. Where does the energy that makes the sparks and lights the tube come from? USW00094728 The material Cross), Forecasting, Time Series, and Regression (Richard T.

Theory When objects are rubbed against each other they acquire electric charge. Electrons moved from sweater to balloon like predicted. charges attract and acts along the line between the two point charges. Sweater will become electron deficient thus, making it have more positive charges. The total negative charge of the electrons is normally exactly equal to the total positive charge of the nuclei, so the atoms (and therefore the entire object) have no net electrical charge. The image shows that the negative charges do repel each other and the positive charges This laboratory activity provides the opportunity to investigate the concepts of static electricity, electrical force, charge, and polarization. Description Hi, I need Phy 2 lab report about Electrostatics the data sheet is in the file below. to make the amount of charge vary. The negative charges quickly left his body as he touched the doorknob as shown below. What do you predict for the answer? To investigate the electrostatic interaction between various objects. always steal electrons from things they come in contact with; others are more willing to give up electrons. Move the rod along and around the top so you touch as much of its surface to the metal of the electroscope as possible. force on the like charges farther away. Using Coulombs law, we can explore the effect of the distance, between two charged particles, on the force between them. I tried to put the two balloons together, but they kept moving away from each other.
