When we beat a carpet by stick the dust particles come out. Which law of motion
works here?
(1) First law of Motion
2 Second law of Motion
(3) Third law of Motion
(4) None of these
Answers
Answer: First law of Motion.
Explanation:
When we beat a carpet by stick the dust particles come out because of the law of inertia. Newton's first law of motion is also known as the Law of inertia.
Law of inertia states that a body remains to be in a state of rest and uninterrupted motion till an external force is applied on it.
The dust particles remains settled in the carpet. When we beat the carpet which is in a state of rest with a stick( stick is the external force applied here on a carpet) the dust particles gets disturbed and leave their place and goes into motion.
Hope this helps.
The 'third law of motion' best suits the reason for dust particle particles comes out from the carpet.
Option (3)
Explanation:
- The 'Third law of motion' is called as for 'every action is an equal and opposite reaction'.
- The two forces are called 'action and reaction forces'. Hence the force applied on beating the carpet removes the dust particles on the reaction by force of action. This better explains the third law of motion.
