Question

2. Define momentum and write its unit. If an object of mass 'm' changes its velocity
from 'u' to 'v' then what will be its:
A) Initial momentum
B) Final momentum
c) Change in momentum
(3)​

Answer 1

Explanation:

ANSWER

Momentum The quantity of motion possessed by a moving body is known as momentum of the body.

Momentum of an object of mass m moving with a velocity v is the product of it.

It is denoted by p

p = mv

Its SI unit is kg-ms-1.

As from Newton’s llnd law, rate of change of momentum is equal to force applied.

Answer 2

Answer:

Momentum is he product of mass of a body and it's velocity.

Explanation:

A): P= m×u

B): P= m×v

C): ∆P = m(v-u)
