Question

Explain how newton's first law is contained in second law?

Answer 1

2nd law gives you F=m.a
Force is directly proportional to acceleration.
Suppose if there is no force then there is no acceleration which means no change in speed and Ist law defines that a body remains at rest on in same motion unless any external force is applied to it. So, when there is no force there is no change in motion. So, 2nd law gives proof for the Ist law.
