Question

Newton's second law of motion and its reason

Answer 1

newtons first law was not so interesting anybody can say that.
But Newton shows his intellegence in second law
He said that momentum will tell how much motion does a body has
and told that
change in momentum is directly proptional to external force applied on a object.

Answer 2

Hey mate..✌

Here is your answer :-


NEWTON'S SECOND LAW :-
=======================

According to it force is directly proportional to rate of change of linear momentum.

F α dp/dt 

F = k dp/dt

Now,

p (momentum) = mv

So,

F = k d(mv)/dt

F = k md(v)/dt

F = k ma

(As, dv/dt = a)

Experimentally k =1

So,

F = ma
