Conservation of momentumContents Survey question: 1Objective: 1Hypothesis: 2Apparatus: 2Method: 2Variables: 3Results: 3Discussion: 7Conclusion: 9Bibliography 9Statement of authenticity 10Investigation question:When In a collision between two objects, is the amount of momentum present in a system before the collision different from the amount of momentum present afterward or is the total momentum of the system conserved. Objective: Prove that the law which states that the total momentum present in a system is conserved is true. Hypothesis: Although the mass and velocity of the moving object will be changed during the collision, the proportion of the change must be such that the total momentum present in the system will be conserved.Apparatus:1. Ticker timer2. Ticker tape3. Ramp4. High table5. 2 thick textbooks6. 2 pieces of mass7. chain method: 1. Place the ramp on a consistently high platform (ensure that the ramp is approximately 1.7 m from the ground)2. Place the manuals under the ramp at one end to tilt the ramp slightly so the cart can overcome friction.3. Tie a strand of string to the front of a cart and tie the other end of the string to a piece of ground.4. Hang the ground piece from the front of the ramp and hold the cart by the angled end.5. Attach tape to the end of the cart (opposite the side where the string is attached).6. Run the ticker tape through a timer and turn the timer on.7. Suspend a piece of mass halfway between where the cart will be released and the end of the ramp.8. Let go of the cart and drop the mass part onto the cart when the cart is exactly below the mass part...... middle of paper ...... links before and after the collision are calculated using times obtained from the electronic timer. This method gives a more accurate volume than the ticker tape method because the factor of human error in the tape analysis is eliminated. (Mann 2013) Conclusion: After the collision, the mass and speed of the object changed, but the total momentum present in the system was not preserved.
