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.
