Question

State newton's second law of motion?Prove that $F=ma$.

Answer 1

Newton's second law of motion states that the force applied to the system is equal to the time rate of change of momentum.

So, $F=\frac{dP}{dt}$

But $P=mv$

So, $F=\frac{d\left(mv\right)}{dt}$

Or $F=m\frac{dv}{dt}$

$⟹F=ma$
