Question

During collision ......….. remains constant. Complete the sentence and explain them.

Answer 1

During collision ......mass/momentum ….. remains constant.
Coz
total momentum of the system just before the collision is the same as the total momentum just after the collision.

Answer 2

Answer:

During collision linear momentum remains always conserved.

Explanation:

During collision no matter elastic or inelastic , linear momentum remains always conserved.Linear momentum always follows the law of conservation.

Momentum is the total quantity of the motion which is stored in the body.

It is denoted by P.

P = m x v

where m = mass of the body , v = velocity of the body.

The S.I unit of P is kg m/s.
