Question

Differentiate between force and momentum. Write the relationship between
them. What will happen to momentum if no external force acts on a body?​

Answer 1

Answer:

Force is a measure of the change of momentum over time. It can be written as F = mass x change in velocity / time. In practical terms, the momentum of an object increases when a force is acting upon it, because the force is causing it to accelerate, and to have an increase in velocity.

Explanation:

According to which, rate of change of momentum is proportional to the applied external force. Therefore, the absence of the external force causes the rate to be zero. Hence the momentum remains constant or conserved.
