Place the calorimeter (no lid) on the balance and tare the balance. In elastic collisions the objects that collide do not stick together, and both continue on with new velocities after the collision. Kinetic Energy Practice Problems 1. a. (c) The balls will move to the right because v1>v2v_1>v_2v1>v2 before the collision. If this was added in to the momentum equation the ration of the final over the initial momentum would likely be much closer to one. b) Load the HCl and NaOH burets with HCl and NaOH solutions, respectively. These results are shown in the table below. This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. Record all data in Table A, and calculate the To answer this question, you really have to think about the moving atoms and molecules as having energy.

The other cart was a plunger cart, which contained a spring activated plunger that could push the carts apart. They were joined together by the Velcro, and the plunger was pushed into the plunger cart. M. Compute the s pecific heat of each type of metal. Its like a teacher waved a magic wand and did the work for me. The slight discrepancies in the values of initial and final momentum can be explained by some sources of error. 1. This cart also had a rod to assist in readings. Then you can change the height of by adding a .75m desk on top of the .95m table. 3. The Logger. The kinetic energy before and after the system was then computed using the above kinetic energy equation.

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. The standard cart moved to a velocity of zero and was still. Did your experiment follow the law of conservation of energy? Use the graph to answer question 2-3. The first step was to graph the distance-time graph from the data collected. In this condition the two carts were placed together in the center if the Photogate Sensors. PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer SOLUTION: Kinetic Energy Student Guide Lab Report - Studypool As mentioned in the research, projectile motion was shown when the marshmallow was launching. In this lab this was analyzed in multiple collision situations. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. 5. Simply put, his law describes the relationship between the mass of an object, the acceleration of an object, and the force needed to move it. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> If you measure it in grams, simply divide the number by 1000 to get kilograms.
