Question

Why do the dust particles come out of a hanging carpet when it is beaten with a stick?

Answer 1

When a hanging carpet is beaten using a stick, the dust particles will start coming out of the carpet because the part of the carpet where the stick strikes, immediately come in motion while the dust particle sticking to the carpet remains at rest. Hence a part of the carpet moves ahead along with the stick, and the dust particles fall down due to the earth's pull.
