Question

newton???s laws and its completeness in describing particle motion

Answer 1

Answer:

Newton describes the motion of the particle by three laws of motion.  

Newton's first law of motion:

When a body is in rest or in uniform motion until the body is obstructed by a particle  

Inertia: the  resistance force offered by the body when a body suddenly comes to rest  

For example:  

When the breaks are applied in a moving bus, a person sitting in it likely to move forward is the best example to understand inertia or motion of the body .
