Question

state the second law of motion ​

Answer 1

Answer:

rate of change of momentum is directly proportional to force applied on an body.

Explanation:

LETS DERIVE THIS

we know that momentum =mv

so change in momentum = mv-mu

rate of change of momentum = mv-mu/t

According to Newton 2 law of motion rate of change of momentum Is directly proportional to force applied

so, mv-mu/t =F

( we know that v-u/t = a )

so, by putting the value of 'a' in equation mv-mu/t

= ma=F
