Question

Show that the rate of change of momentum = mass x acceleration. under what condition does this relation hold?

Answer 1

Assuming that there is not any external force that is acting right on the system, the overall change in momentum is directly proportional to the force applied.

Force can also be called the change in momentum.

Based on all of this, it is clear that rate of change of momentum = mass x acceleration.

This holds true when there is no external force acting on the system.

Answer 2

assuming that there is no external force applied for acting write on the system the overall change in momentum is directly proportional to the force applied
