In our lab work, we had to do multiple tests by dropping a can onto a clay ball. The balls have equal kinetic energies (k1=k2)(k_1=k_2)(k1=k2), but ball 1, which is coming from the left, is moving faster than ball 2 (v1>v2)(v_1>v_2)(v1>v2). 2. What was determined to be true was that the structure that contained the right configuration in producing a high amount of force proved to have the greater amount of displacement of the marshmallow. Velocity is how, The purpose of the experiment was to use previous knowledge of velocity yo perform kinetic energy calculations, make calculations of gravitational potential energy, and to determine what affects GPE and KE more. If you measure it in grams, simply divide the number by 1000 to get kilograms . Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. This taught the very important concept of the conservation of momentum. f. Allow the metal samples to reach thermal equilibrium with the boiling water over the c. Coil the wire around a pencil or other object, or fold the wire tightly to create a more releases or absorbs thermal energy by chemical processes. Record the exact mass in Table B in the row for aluminum, as this will be the first in comparison to white Americans? There are four equations that can be used in both one-dimensional kinematics and two-dimensional kinematics. The initial velocity of the standard cart and the final velocity of the plunger cart were the readings from the first and second Photogate sensors, respectively, on the Logger. 4. The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. rate of fall of an object was determined by its weight held that matter was constructed out. The values of the momentum ratio are very close to one which indicates that the momentum is conserved in the experiment. Do this a few times to find an approximate horizontal distance from the base of the table to where the duck initially contacts the ground. Privacy Policy. 13 chapters | ***Repeat steps 2-4 for each of the following: 5 mL of oil and 2 g each of cornstarch, sodium chloride, and sodium bicarbonate. The Great Depression and the New Deal How did the New Deal affect minorities in the United States (African Americans, Hispanics, etc.) DOCX nca-peterson.weebly.com stream When the standard cart reached the plunger cart they collided, but did not stick together, and the plunger cart moved down the track. increasing). In this condition the two carts were placed together in the center if the Photogate Sensors.

Assemble a coffee cup calorimeter. Ionic bond, table salt. This change and transfer is mediated by one or many forces.Dropping an item from specific heights and weights to see what the kinetic energy measures for each was fun. This experiment will be exploring, in depth, Newton's second law. These values were recorded, and the procedure was repeated two additional times for a total of three readings. If needed, place the Mark the board at 7.5 cm from each end. Because momentum is conserved we can state that the final momentum of a system is equal to the initial momentum of a system in the following equation. 1. compact mass. I'm not able to just leave it out in the public since Reddit will take it down because of copyright, lol. Ionic bonding is a type of chemical bond formed between two ions with opposite charges. The equation for GPE is mass multiplied by acceleration due to gravity, multiplied by height: Acceleration due to gravity is always 9.8m/s2; however, it is acceptable to round this to 10m/s2 for easier calculating. After these values were calculated the ratio of the final kinetic energy to the initial kinetic energy was calculated in order to compare the values. This proved the groups hypothesis. Kinetic Energy Lab Report Edgenuity Answers. The Photogate sensors were used to measure the velocity of each cart as it moved from the explosion site. Momentum cannot be lost in a collision. circle one Measure the height from which you'll be dropping your tennis ball. Set up samples to examine thermal energy transfer with varying material and mass. PDF Lab #5: The Work - Kinetic Energy Theorem - Pennsylvania State University Since it's still and high up, the object only has GPE. This would force the carts to repel each other and not stick together during collision. An example of an elastic collision is a cue ball striking a billiards ball initially at rest. The temperature of the metals should have reached the same The standard cart moved to a velocity of zero and was still. Some of them should be addressed in your lab report. . It is hypothesized that momentum will be conserved in all conditions tested in the experiment. One you have found this distance, focus more carefully on this position so that you can take a measurement from the edge of the table to the position where the duck initially contacted the ground. The initial velocity of the standard cart and the final velocity of the plunger cart were the readings from the first and second Photogate sensors, respectively, on the Logger Proprogram. ,&xZxH|4"z$/Ku%|*62817t>|f'JMnPu/n_zrf~!)r^Vv<3#il4ZI[iiR!hri.#)DnnSpaFKz?WIVFRE7d/~ q|d. In this lab it was found that momentum was conserved in each of the situations above. The kinetic energy before and after the system was then computed using the above kinetic energy equation. Edgenuity, Inc. 3 Mechanical Waves A carries energy through matter. One cart was a standard cart with a rod on top. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni. PDF Kinetic Energy and Motion The fact that the kinetic energy ratio was very far from one shows that the kinetic energy is not conserved in inelastic collisions. The volume is determined by measuring with a ruler and by water displacement. << Suggested Answers 1. c. Observe the increase in temperature every 20 seconds for 3 minutes, or until the bundle These results are shown in the table below. From this point, let The standard cart was pushed towards the plunger cart, which was at rest. Its like a teacher waved a magic wand and did the work for me. Water 100 21 39,0 18 So, multiply your value for height, the mass of the ball, and 10m/s2 to get GPE. % Kinetic factor refers to DGa, activation energy; while the thermodynamic factor refers to DG =G 2-G 1, the driving force. calorimeter into a beaker or other secondary container to prevent wobbling. All objects have momentum, even if it is zero, and momentum cannot be lost. cup, allow the reading to stabilize. Record your time in your data table in seconds. Understanding of DG =G 2-G 1, the driving force A thermodynamically favorable reaction or process means DG < 0, that's to say, highly driven! The final momentum for each condition was calculated using the following formula. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. stated britannica editor Erik Gregerson. After ionic substances dissolve in water, ions separate and become surrounded by water molecules. This allows you to get a more accurate answer. PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer Lab: Kinetic Energy Flashcards | Quizlet Introduction When law enforcement officials investigate car crashes (see Figure L13.1), it can sometimes be difficult to determine who is at fault and what laws were broken, especially when there is no footage of the crash. In this experiment we will prove the conservation of energy by observing the interplay between kinetic and gravitational potential energy. touching the materials to assess their thermal energy. c) Put a clean, dry stir bar inside a clean, dry 50 mL Erlenmeyer flask. The purpose of this lab is to test substances and to determine the physical and chemical properties of substances. Start a timer or note the time on a clock. Time can vary slightly as needed to @W This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. Water 200 20 30 9. I'm remaking this, so it'll be more coherent. in Table A. PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer Step 2: Set up samples to examine thermal energy transfer with varying material and mass. The values of the velocities were shown on the Logger Proprogram. If not, why do you think that happened? Consider the circuit in the diagram. The purpose of the experiment was to find the effect of a balls drop height on its return bounce height. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. 3. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. The conservation of momentum is a very important concept in physics. If you added the amount of KE and heat energy together, you would get the original value for GPE because energy is conserved. Now find KE. Introduce the eight PH indicator strips in the eight . }0@d*>@%-B(B[Q>ND)]Ey%"IV*[]OHqWfjr7fzOSx The ______________ is happening in the presence of conservative forces like gravitational forces or the force in a spring. They were joined together by the Velcro, and the plunger was pushed into the plunger cart. Kinetic Energy Lab Report - 227 Words | Bartleby Dry Sand When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. Why or why not. elasticity.docx - Science | Graded Assignment | Lab Report Think about what you already know about energy. 2 0 obj Answers Energy Types and Transformations Worksheets a. Joule (J) 4. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. PDF WorkKinetic Energy Lab - Physics Classroom (Read Section 7 -3 for a thorough explanation of the W ork-Kinetic Energy Theorem.) The first condition tested was elastic collisions. Pour out some of the water from your soda bottle to adjust the total mass of, water and bottle to 0.125 kg (125 g). Every radioactive element has a different halflife. Identify and describe the transfer of potential energy to kinetic energy. At the level of reference the ____________ is considered equal. The experiment was executed by dropping three different balls of different masses at 100, 75, 50, and 25 centimeters. Before you start, make a prediction: Will the GPE at the top be the same as the KE at the bottom? In the presence of nonconservative forces (like friction), the _____________ is not conserved. Understand the role of the mass in a conservation of energy situation. Anything that has mass and is moving, like a train, a moving ball, or an atom has a certain amount of energy. and securely tape the cylinder to the board with the packing tape. Lab Procedure. Place a small amount of candle wax into a tiny test tube that already has wax in it (scrape it off a tile using a micro spatula). What is the force required to bring the aircraft to a. Attached to the track were two Photogate sensors. e. Measure out approximately 50 g of lead pellets, record the exact mass in Table B, and The goal of the experiment was to identify the gravitational acceleration from the recorded distance(cm) vs time(sec) data of a fallen object. KINETIC ENERGY LAB || Edgenuity || Science Simply Explained by Ivy As the height _________ the GPE will decrease while its kinetic energy increases. We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). m = 150kg . The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors. The percent difference was calculated using the following formula. We'll use a ball to measure potential energy and kinetic energy and examine how the energy is converted from one form to another as the ball falls from a high place. This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. Two clay balls are moving toward each other. You probably found that your values for KE were slightly less than that of GPE. This button released the plunger, and propelled both carts down the track in opposite directions. THERMAL ENERGY TRANSFER LAB GUIDE || Edgenuity Portfolio - YouTube This was a result of miscommunication between group members that proceed to affect why the group had the lowest measurement of displacement. Even thought Ionic bonds still hold molecules together, they are weaker than covalent. In the equation, 404.289cm/s^2(t) represents the slope of the parabolic curve pertaining to the distance(cm) over time(sec) as the 4.876cm displays the y-intercept in which the function crosses the axis leading to the resulting curve. What is your hypothesis (or hypotheses) for this experiment? As usual, you should refer to, 1. This would force the carts to repel each other and not stick together during collision. These sensors were attached to a computer, which was running the Logger Proprogram, through a Vernier computer interface. The standard cart was pushed towards the plunger cart, which was at rest. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. of tape at these points to serve as targets. >> Apply the properties of kinetic and potential energy.
