Question

For each of the cases discuss the following: 1. Knowing that there will bot be perfect conservation of linear momentum in any experimental condition (most notably due to the presence and impact of friction), comment on whether it is expected (theoretically speaking, if there were no frictional forces present) for linear momentum to be conserved during each of the cases being analyzed. 2. Knowing that there will not be perfect conservation of kinetic energy in any experimental condition (most notibly due to the presenece and impact of friction), comment on whether it is expected theoritically speaking, if there were no frictional forces present) for kinectic energy to be conserved during each of the cases being analyzed, and state if it is therefore expected to be an elastic collision or inelastic collision.

Explanation / Answer

1) Linear mom is not likely to be conserved with external forces present. If there are no frictional forces, linear mom is conserved in case of the collisions, elastic or inelastic. 2) Yes, KINETIC ENERGY can be conserved in case of ELASTIC collisions, given that there are no frictional forces. KE Is not conserved in case of inelastic collisions as some kinetic energy is lost in the form of collision potential energy. Hope that clears it. Did you like my detailed explantion?
