When a coat/blanket is beaten by a stick, the dust particles are removed. This is in accordance with which of the following?

Newton's first law of motion

Newton's first law of motion: Everybody maintains its initial state of rest or motion with uniform speed on a straight line unless an external force acts on it. First law is also known as law of inertia.

Inertia: It is the property of a body by virtue of which the body opposes change in its initial state of rest or motion with uniform speed on a straight line.

Inertia is of two types:

1. Inertia of rest

2. Inertia of motion

Some examples of Inertia/first law:

1. When a car or train starts suddenly, the passengers bend backward.

2. When a running horse stops suddenly, the rider bends forward.

3. When a coat/blanket is beaten by a stick, the dust particles are removed.
