Conservation of momentum. ( ) - Lab Report ExampleConclusion gave information concerning the realization of the intended purpose of the entire essay as per the relayed hypothesis, which is in the introduction section. Introduction Information or data obtained by and by the commencement of this experiment will be essential in determine the extent and effect of conservation laws. This was via utilizing effects of collision prior to and afterwards and encompassed measuring respective quantities of energising energies of the involved bodies. The apparatus used for this purpose was ballistic pendulum and a ball propelled horizontally on a flat surface to hit a stationery pendulum at a certain velocity. Data fetching was before and after collision, which were essential in muster intended comparisons regarding momentum conservation. This is by pickings Kinetic energies of the colliding body with that which is stationary to help in drawing conclusion regarding their respective condition s or states both before and after collision has taken place. Theoretical hypothesis in this experiment encompassed preservation of a mournful bodys total momentum except in the case of interruption by an external force. Therefore, kinetic nothing data obtained prior to and after collision entailed to affirm conservation principles of linear momentum. Essential equations that were in use for this experiment include, 1. Initial velocity Vi = d/t 2. Initial kinetic energy KEi =1/2mvi2 3. Initial Momentum Pi =mvi 4. Final velocity Vf =v2gR (1-Cos?) 5. Final Kinetic Energy KEf = ?(M+m) vf2 6. Final Momentum Pf = (m + M)vf Procedures 1. Initial step encompassed taking measurements of, Mass of the ball Mass of pendulum Pendulums radius starting from its pivotal point towards the mass center 2. Then the positioning or setting up of the photogate followed but after removal of pendulum from apparatus that was in front of the propelling launcher. 3. There was opening of convenient data colle ction tool in a computer whose role encompassed recording results for easy evaluation, comparison and computations. 4. Then loading of plastic ball into the ballistic pendulum took place. 5. In this step, it entailed measuring distance starting from outermost edge of one photogate eye to the second photogate eye then followed by recording the data, which was the first mental test. 6. The practical part of the experiment commenced with firing of ball via the photogate gather and then taking the amount of time it took to go through the photogate for each trial. In addition, there was also taking of distance measurements separating photogate eyes for each trial because it they were subject to change after each propelling trial of the ball. 7. After the sixth step, the obtained data of time in seconds and distances in meters were essential in figure respective velocities for each trial coupled with tabulating the data in the results tables. There was also the need of computing overa ll mean velocity for the ten trials as well as standard deviation for each propelling time of the ball. 8. The already obtained data (mean velocity) of the ten trials its purpose was to calculate initial kinetic energy and momentum with the aid of equations (2) and (3). 9. After the first experiment section, there was dissembling of photogate and mounting of pendulum in such a way it swung freely. This is by ensuring once
