Repeat the procedure if necessary, pushing the sliding ball up until it touches the hanging ball. Open John Travoltage at phet.colorado/en/simulation/john-travoltage When objects are rubbed against each other they acquire electric charge. Arrange the objects in two categories according to their cha. A. The lab helped explore concepts of static electricity and discover how many types of electrical charges exist and how they interact with each other. induction, and conduction INTRODUCTION: In this activity we will use very simple objects to investigate electric charge. Your matched tutor provides personalized help according to your question details. If the humidity is extremely low, as is often the case in Southern California, you will probably not escape the lab without a direct experience with electrostatics! Include in the discussion the vocabulary: charge transfer and electric attraction. Experiment Title: Chemical Equilibrium and Le Chateliers Principle. \end{eqnarray}. Volume 1 covers mechanics, sound, oscillations, and waves. 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. Login projectile motion refers to design and light. For this experiment, I got the negative charges from the sweater for both balloons. Gold was used because it is a good conductor and very ductile; it can be made very thin and light. much stronger repulsion than when the non-sticky sides face each other. The plate actually makes contact with the lucite in only a few places; and because lucite is an insulator, charge does not transfer easily from it. As shown in the demo below, the sweater is positive and the balloon attaches to the Place the metal plate on the center of the lucite plate, and touch it with your finger. pulling or pushing. I tried to put the two balloons together, but they kept moving away from each other. Touch his finger to the door knob to show grounding. https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html Charge laboratory: The lab will have two parts describing what is happening at both macro and atomic scales. 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 answers from #2 and #3 support the results from the investigation since the Reflect on your answer to #6, write down any new ideas that you have. Have a class from the sweater then putting it up against the wall once it was filled with the negative charges. The material losing electrons now has fewer electrons than normal and becomes positive. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below. Entertainment & Pop Culture; Geography & Travel; Health & Medicine; Lifestyles & Social Issues; Literature; Philosophy & Religion; Politics, Law & Government Touch the lucite rod to the top of the electroscope. 4.Ask Reflect on your answer to #2, write down how your thinking has changed. Have a class discussion. Devise and execute an experiment to verify the dependence of the Coulomb force on the value of one of the charges. It is referred to as a "proof plane". Please write answers direct on the PDF file. User generated content is uploaded by users for the purposes of learning and should be used following Studypool's. This lab can be done with different materials found at home. remain despite the sides the two tape pieces face. One common demonstration performed with the electroscope involves the induction process of charging. Since the rod is an insulator, charge will not flow from all parts of the rod onto the electroscope; you need to touch all parts (except where you are holding it) to the electroscope. Use a Google Spreadsheet to document your data, graph and determine the equation for the relationship. i. What do you predict for the answer? Materials: Recharge the balls as in steps 1 4, and record a series of measurements of the inside edges of the balls. Determine the relationship between distance and the strength of the electric field around a charged body. The measurements done with the micrometer obtained the highest number of significant figures for the thickness of a single sheet of text book paper. Record the time it takes the electroscope needle to fall completely to 0. This film conducts away the charges before they have a chance to build up. You can record and graph data in Excel or by hand (although if you work by hand, you will lose the opportunity for 2 mills of additional credit below). Move the rod along and around the top so you touch as much of its surface to the metal of the electroscope as possible. We say that the rod has induced polarization in the insulator, but its net charge is still zero. Electric charge comes in two forms: positive and negative. measurements. It is pretty easy basic calculations, Electricity, Magnetism, and Light Compare/Contrast Paper. 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. electrons leave the plate and enter the needle, both plate and support/needle acquire an imbalance Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Educational Research: Competencies for Analysis and Applications (Gay L.

Hard rubber rods, which are also commonly used, become negatively charged. d. How would the arrows look if the puck was negative? different fabrics, such as cotton, silk and wool One of these is silver. Describe the materials and fabrics that you found: Electrons are essentially being transferred from the balloon to the sweater. STATION If a neutral material is placed inside a weak electric field, it will not experience a net force, Rub the lucite rod vigorously with the silk cloth. USW00094728 In most of the exercises, you do not take data, but record a short description of your observations. Use Google Spreadsheet to document your data, graph, and Slide 1 of 4. attachment_1. Observe what happens with the neon tube. Static A new classified U.S. Dept. If the needle has not fallen to 0 after five minutes, record an estimate of its angle at the five-minute mark. It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. if you use two of the same ones exactly opposite to each other, they would also cancel out and the puck would be stationary. In this simulation, a little different model is used. The word electricity comes from the Greek word electron which means amber (a tree resin that If you make a mistake with the program you can start over by closing the program without saving and opening it again from the Desktop. With the electroscope deflected as a result of the operations above, bring the charged lucite rod near the electroscope again. Bring it near your lab partner's knuckle. Students also viewed Physics 2 lab report Coulomb's Law Ohm's law - Lab report A neutral balloon will gain electrons from the sweater. You can do this with the We are all familiar with the fact that cold, dry days are hot for electrostatics, and we get small shocks after walking across a rug and touching a door knob, or sliding across a car seat and touching the metal of the car door. Slide the block into the Coulomb apparatus without touching the sides of the box with the ball. The force triangle of Figure 10 gives, \begin{eqnarray} \tan\phi &=& F/mg, \end{eqnarray}, while the physical triangle of the hanging ball gives, \begin{eqnarray} \sin\phi &=& d/L. Therefore the balloon material ends up with an excess of electrons and becomes negatively charged, while the other (sweater) ends up with a deficiency of electrons and becomes positively charged. What do you predict for the answer? Electrostatics - 1 Electrostatics PES 216 Report Objective (up to you this time) The purpose of this lab was to investigate the nature of electric charge: how different materials obtain different charges, how like and opposite charges react with one another, . The reason of why electrolytes or ionic compounds are supposed to conduct electricity is because of the charge of the molecule, ionic . Estimating the charge of one . equal to 9 x 10 9 N 2 /C 2. The force is proportional to the product of the magnitude of the charges. Compute columns of displacements \(d\) (position of the hanging ball minus the equilibrium position) and the separations \(r\) (difference between the two recorded measurements plus the diameter of one ball). The plate acquires an excess of positive charge (since electrons have left this once neutral region) and the support/needle acquires an excess of negative charge (since electrons have entered this once neutral region). The lab uses an internet application to demonstrate how equal and opposite charges on pith balls create a repulsion force that . If the humidity is high, as it is sometimes in the summer, the experiments are more difficult, and some may be impossible. AMERICAN UNIVERSITY OF SCIENCE & TECHNOLOGY FACULTY OF ENGINEERING DEPARTMENT OF COMPUTER AND COMMUNICATIONS ENGINEERING CIRCUIT ANALYSIS 1 LAB CCE 201L Report # 2 DMM-Power Supplies-Soldering Techniques-Making PCBs Prepared by Daniel Khazaal Presented to Dr. Nashaat El Halabi February 26, 2016 Achrafieh Campus Include in the discussion the vocabulary: electric repulsion; compare with charge Place the rod into the stirrup holder as shown in Figure 7. the positive charge would pull and the negative charge would push. We are all familiar with the fact that rubbing two materials together for example, a rubber comb on cat fur produces a static charge. If two objects are charged in the same way, they show repulsion. The study of the Coulomb forces among arrangements of stationary charged particles is called electrostatics. The charges tend to accumulate on the surface of the balloons. Would you like to help your fellow students? Electrostatic Lab [1] Purpose: To determine the charge and charge distribution on insulators charged by the triboelectric effects and conductors charged by an Electrostatic Voltage Source. 54 Comments Please sign inor registerto post comments. 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 . Is there any difference in the behavior of the needle compared to the results in procedure 6? Other materials such as glass are insulators. Our verified tutors can answer all questions, from basicmathto advanced rocket science! What is the average distance a spark will jump? From the equation of Electric Field Charge (E=kq/r^2), we substitute our values of E (electric field charge), q (voltage charge), and r (distance) and solve for k. Solving for k, would give us the slope of the line m = k/r^2. 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 A conductor will carry an electrical current.
