Question

in intermediate the lesson motion in a plane examples for inertia

Answer 1

There are two types of inertia:

1. Inertia of motion: when a ball is rolling on a frictionless floor with constant velocity, it will keep rolling with the same velocity unless an unbalanced external force acts on it.

2. Inertia of rest: Keep a book on a table in rest. The book will be in resting position unless an unbalanced force acts on it.

Answer 2

Inertia of motion :when a bus is moving very gently as if driver suddenly if driver apply brakes we will fall front. this is inertia of motion
Inertia of rest: when bus is still and if it suddenly starts moving we will fall backwards. this is inertia of rest
