Question

Newton's second law of motion

Answer 1

second law of motion state the rate of change of momentum of an object is directly proposal to the apply unbalanced force

Answer 2

$\huge\textbf{Law of Force :}$


It is Newton's Second law.

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

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,

$\textbf{F = ma}$
