4. Define momentum. Write its S.I unit
5.Name the force which is responsible for change in position or state of an object.​

Answer 1

Explanation:

When a carpet is beaten with a stick, the dust comes out of it because of law of inertia.

Initially the dust particles are at rest along with the carpet. Beating the carpet with the stick makes the carpet to move but the dust particles remain at rest due to inertia at rest, thus the dust gets detached from the carpet This is your answer 2
