Question

Why is newton 2nd law a real law?

Answer 1

Answer:

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.

Answer 2

The second law of physics is a real law because it proves the first law i.e. If a body is in rest it will be in rest and if a body is in motion it will be in motion.

So, if F=0 A will be also 0

Which proves that the body is in rest and if the F is not 0 it means the body is in motion
