Priyanjal Mishra 7 years, 3 months ago

Which states that there will be no acceleration in the body if no external force is applied on it.This means that a body in rest will remain at rest and a body in uniform motion will remain in uniform motion which is also stated in Newton's 1st law. ... Therefore,2nd law of motion is a real law of motion.
