Question

write the nention's 2nd law of motion and prove that F=ma

Answer 1

Hay mate here is your answer ✌❤☺



Newton's 2nd Law of Motion: Rate of change of momentum(p) is directly proportional to the force(F) acting on it in the direction of force. Hence Proved (was dying to write this at the end, nostalgic. Here is the second law with explanation and derivation. :) Force equals mass times acceleration.,



Hope it will help you ☺❤

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,

$\textbf{F = ma}$
