Question

what is momentum?how does it work what is it's S.I. unit​

Answer 1

Momentum is the product of mass and velocity. Its S.I unit kg metre per second. It can alse be defined as mass in motion.

Answer 2

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg. m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.
