Answer 1

Dear student,

Inertia is the resistance, of any physical object, to any change in its velocity. This includes changes to the object's speed, or direction of motion.

Or

It is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.


Consider example situations in figure
