Question

What is the time rate of change of momentum called?

Answer 1

1. According to Newton's second law, the rate of change in momentum($p$) of an object is equal to the force$\left(F\right)$ applied.
2. $F=\frac{dp}{dt}$
3. The unit of force is $\mathrm{Newton}(\mathrm{Kg}{\mathrm{ms}}^{-2})$.

Therefore, the time rate of change of momentum is called force.
