Question

The formula of force with the help of Newton 2nd law of motion​

Answer 1

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m.

Answer 2

Answer:

F = m a

Explanation:

If a body of mass "m" moving at initial velocity "u" accelerates uniformly with an acceleration "a" for time "t" so that it's final velocity changes Into "v".

then initial momentum p1 = mu

final momentum p2 = mv

change in momentum = p1-p2

= mv-mu  

= m(v-u)

according to 2nd law of motion  

F = change in momentum / time

F = p2-p1 / t

F = m(v-u)/ t

F = ma 《 v- u / t 》
