Question

explain 2nd law of motion in detail.

Answer 1

the second law of motion is.....
force is directly proportional to the change in momentum and inversely proportional to the time taken.....
it literally means that......when there's a large change in momentum in less time....... force too becomes large.....
and when there's change in momentum in large time.... there'll be less force.........

by solving this law you'll left with

F=ma
in which mass and acceleration are inversely proportional.........

i.e. when mass increases the acceleration decreases.........and vice versa!!!!!

but there'll be no change in force....
that's it!!!
