the rate of change of momentum is proportional to m(v-u)/t or is equal to it.kindly explain.

answered-by-expert Expert Answer
Momentum is defined as : p = mv
thus rate of change of momentum clearly is m(v-u)/t
Dont confuse it with the second law of motion.
It says that force is proportional to rate of change of momentum.
i.e F is directly proportional to m(v-u)/t
