Question

Can the internal forces acting among the parts of a system change the linear momentum of the system ?

Answer 1

no...bcoz momentum is the product of mass and velocity and there is no need of force

Answer 2

Given that,

The internal forces acting among the parts of a system change the linear momentum of the system.

We know that,

Momentum :

The momentum is equal to the product of mass and velocity of the object.

In mathematically,

$P=mv$

We know that,

If the internal forces acting among the parts of a system then the linear momentum of the system will not be change. Because we need mass and velocity for momentum not force.

Hence, No change in the linear momentum of the system
