When a carpet is beaten, dust comes out due to the principle of inertia. The carpet is set into motion, but the dust particles, being at rest, tend to stay at rest due to their inertia. This difference in motion causes the dust to detach from the carpet and fall out.
Here’s a more detailed explanation:
Inertia:
Inertia is the tendency of an object to resist changes in its state of motion. An object at rest wants to stay at rest, and an object in motion wants to stay in motion.
Carpet Motion:
When a carpet is beaten, it is suddenly set into motion by the force of the stick.
Dust’s Inertia:
The dust particles inside the carpet are initially at rest. Due to inertia, they resist the change in their state of rest and don’t immediately move along with the carpet.
Dislodging the Dust:
As the carpet moves, the dust particles, being at rest, tend to remain in their original position. This causes the dust to become dislodged and fall out of the carpet.
