Question

What is the Newton's 2nd Law?

Answer 1

Newton's 2nd law:-
the acceleration of an object as produced by a net source is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object

Answer 2

According to Newton's second law of motion, the rate of change of momentum of a body is directly proportional to the force applied on it and the change in momentum is in the direction of force applied.
Force(F)= $\frac{Δp}{Δt}= \frac{Δmv}{Δt}$
Δm=change in momentum,
Δt=time,
Δv= change in velocity.
