Explain the inertia of rest through some examples.

The inertia of rest is the tendency of a body to remain at rest until an external force acts on it.

Inertia is a property of matter that resists changes in its state of motion. The inertia of rest specifically means that an object will not move by itself unless an external force causes it to move. This concept is described in Newton’s First Law of Motion.

Examples of Inertia of Rest:

1. Book on a Table: A book remains at rest until someone pushes it.
2. Passenger in a Bus: When a stationary bus suddenly starts, passengers jerk backward because their bodies resist motion.
3. Ball on the Ground: A ball will stay still unless someone kicks it.
4. Dust from Carpet: When a carpet is shaken, dust particles fall off because they resist moving with the carpet.
