Question

Define momentum.

Answer 1

Momentum:

1. A physical quantity which depends on mass and velocity of a moving body is called momentum.
2. It is defined as $momentum=mass\times velocity$
3. $p=m\times v$ , where $p=momentum,m=mass,v=velocity$
4. It is a vector quantity.
5. Unit of momentum in S.I. system is $kgm{s}^{-1}$.
6. Unit of momentum in C.G.S. system is $gcm{s}^{-1}$.
7. $1kgm{s}^{-1}={10}^{5}gcm{s}^{-1}$.
