To what do you attribute the percent difference in KE and KE\' in the elastic collision? Do your results show kinetic energy to be conserved? Is the total energy conserved? 3. To what do you attribute the percent difference in KE and KE\' in the inelastic collisions? Is kinetic energy conserved? Is the total energy conserved in these collisions? Explain 4. 5. Suppose the air track were tilted during the experiments. Would momentum be conserved in the collisions? Why or why not? 108 Solution Solution: 3. Description: For in the elastic collision, non-constant velocities and frictional losses make the differences between them. This shows the KE in the elastic collision is to be conserved. 4. Description: For in the elastic collision, the Kinetic Energy is not preserved. But, though it is conserved for the total energy. From this it observed that, energy can be converted into any other forms such as heat, sound and deformation of wax which are in the primary forms. 5. Description: For this-momentum is to be preserved, yet it is due to the tilting experiment which would go to be accelerating. This means that the momentum is conserved & which won’t be the proof for the respective experimental setup. .
