electrostatics lab report conclusion

So the balloons did move away from Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon on the wall it will stay up and attached to it. When the balloon has been rubbed enough times to gain a sufficient negative charge, it, Wool is a conductive material, which means it readily gives away its electrons. The Essay on Formal lab report on ionic and covalent compounds. This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below. Surrounding a charge there is an invisible electric field which gets weaker the farther away one gets from the charge. Lift off the metal plate by its insulating handle, and touch it carefully to the ball on the left sliding block. remained. This lab can be done with different materials found at home. Now remove the lucite rod. When we charge a material by friction, we are transferring some of the electrons from one material to another. Copyright: Some positive charges in the wall will move towards the balloon. Typically, lab reports present data, discuss results, and provide conclusions. Be prepared to start your timer. Conclusions Can you conclude that one disk has a tendency to become positively charged and one What do you predict for the answer? Sticky Tape Experiments Lab Included, labeled and organized all parts of the lab report. Recharge the lucite rod with silk. Great content here. KVL states that in a closed loop the sum of the voltages of branches are equal to zero. B. game. Use a Google Spreadsheet to document your data, graph and determine the equation for the relationship. material, positive and negative charges are no longer randomly distributed and are slightly I tried to put Number of CONCLUSION. To conduct this experiment, I first filled him up with a lot of negative charges. At this point electrons will flow between the electroscope and the ground, giving the electroscope an overall charge. (They are linearly proportional). where r is the distance between the two charges and k is called the proportionality constant and is equal to 9 x 109 N.m2/C2 . Using Coulombs law, we can explore the effect of the distance, between two charged School. Why can you use either a positive charge or a negative charge to move the positively In its present form, the electrophorus consists of a lucite plate on which rests a flat metal plate with an insulating handle. Now if we connect a conducting wire or any other conducting material from the polarized conductor to the ground, we provide a path through which the electrons can move. and protons carry positive charge. Recharge the metal plate, and bring it slowly near the top of the electroscope. USW00094728 Nevertheless, a charged object will attract a neutral macroscopic object by the process of electrical polarization. Discuss the methods used. Most materials are electrically neutral they have an equal Step 3: Add an extra bulb into the circuit loop. The arrows would be opposite to what the picture displays. 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! slightly electrocuted. 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. The hanging ball should be repelled strongly. Experiment Title: Chemical Equilibrium and Le Chateliers Principle. go twice as fast towards the negative charge puck. Charge sticks on an insulator, but does not move freely through it. Not all steps have observations to record. If the negative rod is brought near an isolated, neutral conductor, the conductor will also be polarized. i. Bring up John Travoltage. Observe what happens with the electroscope needle. Please help with lab report discussion and conclusion. Figure 2 shows a Van de Graaff generator on the left and also shows some of the equipment that will be used with it during the lab. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. Theory When objects are rubbed against each other they acquire electric charge. 10 Lab 1: Electrostatics Vanderbilt University, Dept. Neutral particles do not interact with electrical forces. different fabrics, such as cotton, silk and wool. (Refer to the theory section, if necessary.). (phet.colorado/en/simulation/john-travoltage). 2. State Whether Your Experiment Succeeded. (transfer of charge, induction, attraction, repulsion, and grounding). When rubbed, a piece of amber can attract small objects like tiny pieces of Most electrons will go into the knob and down to the earth. In this section, you charged the lucite plate by rubbing it at the beginning, and were then able to charge the metal plate repeatedly. The direction of this force is determined by the sign of the charges: like charges repel and unlike What do you think the arrows on the puck are illustrating? 286 Comments Please sign inor registerto post comments. Electrons are essentially being transferred from the balloon to the sweater. If the angle \(\phi\) is small, then \(\tan\phi = \sin\phi\), and \(d\) is proportional to \(F\). When charge is brought near the top electrode, the movable vane moves outward, being repelled by the fixed vane. For an additional credit of 2 mills, use Excel to fit a power-law curve to the data. 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). Talk about the similarities and differences in the two models represented by the sims. The metal plate is negatively charged by induction. and rubbing his foot on the carpet, once he touches the door knob that is metal he is shocked or to make the amount of charge vary. Wool is a conductive material, which means it readily gives away its electrons. 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). Access over 20 million homework documents through the notebank, Get on-demand Q&A homework help from verified tutors, Read 1000s of rich book guides covering popular titles. Hard rubber rods, which are also commonly used, become negatively charged. These equations will verify this statement: -Vs+Vr1+Vr2=0-5v+1. Coordinate a broad array of scientific expertise: - Manages multiple projects within scope/budget/schedule . Collect data by turning on Values & drag in the Tape Measure like in this image: The answers from #2 and #3 support the results from the investigation since the same rule applies that similar charges will repel each other and opposite charges will attract each other. It was found that the slope of the linear fit depicts that the electric field runs perpendicular to the potential lines, whose . Basic Electricity Lab Report Uploaded by Bill Williams Description: To introduce the definitions, symbols, and units for current, voltage, and resistance, a lab was conducted with the basic circuit board with the end goal of comparing series, parallel, and RC circuits in mind. Coulombs Law: https://phet.colorado.edu/sims/html/coulombs-law/latest/coulombs-law_en.html. electrochemistry-lab-report-conclusion 2/5 Downloaded from uniport.edu.ng on March 3, 2023 by guest reaching down even to the molecular level. illustrates the direction of the field in a positive and negative charge. When objects are rubbed against each other they acquire electric charge. What happens in each case? Your eye is now perpendicular to the scale, and you can read off the position. Restate the Experiment's Goals. Title / Cover Sheet: use the provided cover sheet. 1. Electrons are being transferred from the balloon to the sweater. Step 4: Note down the reading on the ammeter. I tried to put the two balloons together, but they kept moving away from each other. Physics Lab Report. Figure 1. discussion. 2 1 m 12 V 8 V/m Conclusion/Discussion Observe what happens with the neon tube. The conductor has been polarized, and will now be attracted to the charged rod. At the bottom of the rod, very thin gold leaves were folded over hanging down, or perhaps a gold leaf hung next to a fixed vane. What can we do to change some of the problems?Cite Plea 4.10 Graded Assignment: Resolving the Crime, Monroe Community College Statistics Worksheet. Here you explain why you got the answer that you did (5: 164-171). illustrates the direction of the field in a positive and negative char. around a charged body. Electrons carry negative charge A conductor will carry an electrical current. Once a charge is is placed inside a strong electric field, the material may become polarized. remain despite the sides the two tape pieces face. So the balloons did move away from each other. The material gaining electrons now has more electrons and becomes negative. Question 3: What do you think the balloons will do? Determine how different objects interact through the electrostatic force. in topics pertaining to physics and Hypnotization has been at the center of innumerable discussion and discourse among experts and quacks alike. 1. (V/m) This experiment consists of many short demonstrations in electrostatics. (Sometimes it is necessary to touch different parts of the rod to the balls.) After writing this essay, I have realized the importance of electrostatics in our lives. If the experiments are difficult on the first week of the electrostatics lab, they will be left up so you can try some of them with the Van de Graaff experiments in the following lab. The magnitude of the electrostatic force between two-point charges ql and q 2 is given by Coulomb's with sharing and discussing. However, if a neutral object You must use appropriate significant figures and scientific notation in your answers. Although the wall should normally have a neutral charge, the charges within it can rearrange so that a positively charged area attracts the negatively charged balloon. Values of Thickness 2. Consequently, This way, you can obtain charges on the first ball of \(Q\), \(Q/2\), \(Q/4\), and so forth. This is an electric field and electric potential lab. To investigate the electrostatic interaction between various objects. Content Type. They are composed of atoms that consist of negatively charged electrons moving in quantum motion around a positively charged nucleus. USW00094728 Determine the relationship between distance and the strength of the electric field around a charged body. Plastic rubbed with wool/silk/cotton/any other material, Wood rubbed with wool/silk/cotton/any other material, Glass rubbed with wool/silk/cotton/any other material, Rubber rubbed with wool/silk/cotton/any other material, Username is too similar to your e-mail address, Introduction to Electrostatics Lab Report. The lab TA will provide more instruction. Write how the results of your However, if a neutral object is placed inside a strong electric field, the material may become polarized. if you use two of the same ones exactly opposite to each other, they would also cancel out and the puck would be stationary. 562v=0v2) Verify KCL in figure 3 circuit from hardware measurement. Use a little whipping motion at the end of the rubbing. equal to 9 x 10 9 N 2 /C 2. In this simulation, a little different model is used. Step 5: Add a third and . Usually the lucite needs to be charged only once for the entire experiment. Start each observation with the section number and step number (e.g., I-2 for the step below). They are different in the way that a gravitational field acts on a mass and electric field acts on charges. KCL states that the current entering a node is equal to the current leaving it. Critique the lab and describe opportunities for further / future work. Stuck on a homework question? (Do not confuse electrical polarization with the polarization of light, which is an entirely different phenomenon.). Questions are posted anonymously and can be made 100% private. Question 4: What might happen to the charge on the man when he touches the doorknob? Instead, when you touch the metal plate, electrons from your body (attracted by the positive lucite plate) flow onto the metal plate. Recharge the sliding ball so it produces the maximum force, and experiment with pushing it toward the hanging ball. The force is proportional to the product of the magnitude of the charges. There is a tall box containing a hanging pith ball covered with a conducting surface, and similar pith balls on sliding blocks. same between the two charges. You are going to measure the displacement of the hanging ball. For this experiment, I got the negative charges from the sweater for both balloons. The side which the tape faces matters only in terms of the degree of attra. User Generated. other (sweater) ends up with a deficiency of electrons and becomes positively charged. Then bring the rod near one of the balls. Make sure that they understand that this is commonly called grounding. What do you predict for the answer? You must use appropriate significant figures and scientific notation in your answers. Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. If the sticky side of both the tape. The lab helped explore concepts of static electricity and discover how many types of electrical charges exist and how they interact with each other. Materials: charges attract and acts along the line between the two point charges. Hold the metal plate by its insulating handle as far from the metal as possible. Bring the lucite rod close to (but not touching) the pith balls. Two particles of the same charge exert a repulsive force on each other, and two particles of opposite charge exert an attractive force on each 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 . surface. Gold was used because it is a good conductor and very ductile; it can be made very thin and light. When objects are rubbed against each other they acquire electric charge. You may use the stopwatch function of your wristwatch. Electric field lines are typically drawn to visualize the field. The puck will move horizontally right if both the magnitude and the distance were the grounding. Slide the block in until it is close to the hanging ball. USW00094728 Introduction Electricity is an essential part of the modern life experience, and as an engineer it is essential to know how it behaves and responds to changes in its trajectory. will have a stronger attractive force on its closest charges of opposite sign and a weaker repulsive (Refer to the theory section, if necessary.). The balloons will move away from each other. Record this distance in your notes. Bring the lucite rod near the electroscope again so that it is deflected. This USB port seemed to have very high amperage, meaning it charged her phone quickly. Performing experiments and writing lab reports provide hands-on experiences with engineering concepts and devices. With the electroscope deflected as a result of the operations above, bring the charged lucite rod near the electroscope again. User. It is pretty easy Astronomy Lab due. : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Charge the electrophorus lucite plate by rubbing it with silk. They are classified as Nan-electrolyte compounds. B. It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. During the few days after your assigned lab period: Meet with your lab partners to plot and/or reduce your data, to draw conclusions, and to the group lab report.
