Question

What is Newton second law

Answer 1

Answer

According to second law of Newton "applied force on a body will be equal to change rate of momentum".

So

$F=\frac{d(P)}{dt}$

Where "F" is force and " P" is momentum.

And

$P=mv$

So

$F=\frac{d(mv)}{dt}$

If mass is constant then

$F=m\frac{d(v)}{dt}$

And $\frac{d(v) }{dt}=a=acceleration$

So

$\colorbox{aqua}{$F=ma$}$
