When a carpet is beaten with a stick, dust comes out of it. Explain.

Answer:

An object’s inertia tends to resist any change in its state of rest or motion. If a carpet is beaten with a stick then the carpet begins to move. But, the particles of dust are trying to resist their state of rest. The dust particles remain in a state of rest, while the carpet moves, as per Newton’s first law of motion. The particles of dust thus emerge from the carpet.
