Question

State Newton’s second law of motion. Derive a mathematical expression for Newton’s second law. Short

Answer 1

In summary calculating force is directly proportional toM (v-u) /t

The rate of change of momentum of a body is proportional to the applied for and takes place in the direction in which the force acts

Answer 2

It states,"The rate of change of momentum is directly propotional to the applied force and the change takes place in the direction of the applied force".
By newton's second law of motion we have
F=change in momentum over time.
now, mv -mu
F=m(v-u)over t
But(v-u)over t =a
Therefore,F=ma=mass×accerlation
Therefore F=rate of change of momentum.
i hope it will help you..
