Question

what is inertia of motion

Answer 1

Anything with mass has inertia, and it can move. It does not have to move in order to have inertia. Inertia is the tendency of mass to remain in a constant motion, unless a force causes a change in that motion. Zero motionis also a state of constant motion. ... You, the car and the violin all have inertia.

Answer 2

The resistance offered by a body to change its state of uniform motion is called inertia of motion....
For example an athlete runs for a while before taking a long jump the motion gained by the athlete helps him to take a longer jump.
