When a coat/blanket is beaten by a stick, the dust particles are removed. This is in accordance with which of the following?
Answer & explanation
Correct answer: option 2
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.
