Question

In absence of external force the change in momentum is zero or constant ?

Answer 1

the change in momentum is zero............

Answer 2

Concept Introduction: Momentum is a very basic concept in the Newtonian Physics.

Explanation:

We have been Given: Momentum of a body.

We have to Find: In absence of external force the change in momentum is zero or constant?

In absence of external force the change in momentum of a body will be zero. Because if there is a change in external force, the velocity will be affected of the body, and we also know that Momentum is given by

$p = mv$

if the external force is absent that means,

$m \frac{dv}{dt} = 0$

therefore, the momentum will be zero.

Final Answer: In absence of external force the change in momentum of a body will be zero.
