State and prove Newton's second law of motion... 9th Class Question...

Answered by admin @ 24/08/2021

Answer:

Newton's Second Law of Motion states that the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body.

So,

F= $\dfrac{dP}{dt}$

But P = mv

So,F = $\dfrac{d(mv)}{dt}$

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

⟹ F = ma
