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

Short Answer

Solution

  • The inertia of an object tends to resist any change in its state of rest or state of motion.
  • When a carpet is beaten with a stick, then the carpet comes into motion. But the dust particles try to resist their state of rest.
  • According to Newton’s first law of motion, the dust particles stay in a state of rest while the carpet moves. Hence, the dust particles come out of the carpet.
