Question

Can the dust out of a blanket be removed using the law of inertia?

Answer 1

Law of Inertia:

1. It is also known as Newton’s first law of motion.
2. It states that an object will continue to be in the state of rest or in a state of motion unless an external force acts on it.

Types of inertia:

The following are the types of inertia:

1. Inertia of rest: When the resistance is offered by the body to continue in the state of rest unless an external force acts on it.
2. Inertia of motion: When the resistance is offered by the body to continue to be in the uniform motion unless an external force acts on it.
3. Inertia of direction: When the resistance is offered by the body to continue the motion in the same direction unless an external force acts on it.

Explanation:

1. According to the law of inertia, a particle tends to stay at rest or in uniform motion unless pushed upon by an external force.
2. When you hit the blanket, it moves, but the dust particles remain at their original position and the dust is eventually separated as under the action of gravity, it falls down on the ground.
3. When we beat the blanket with a stick, it comes into motion.
4. However, due to inertia, the dust particles stay at rest and separate from the blanket.
