Show that Newton's second law of motion is real law of motion.

Answer»

Other LAWS of NEWTON can be derived from Newton's second law. Hence it is called REAL law of Newton

For eg…

2nd law is…F=ma

And 1ST law is …initial velocity=final velocity

Assume that force acting on body is zero

F=ma

so…0= ma

0/m = a

0=a

0= (v-u)/t

0/t = v-u

0= v-u

U=v

Thus ….we PROVED that 1st law can be derived from 2nd law of Newton
