Question

why does an athlete run some steps before coming to halt after reaching the finish line?

Answer 1

Dear Student,

It is due to the inertia of motion. The law of inertia states that:
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called. "the law of inertia".
