Which of these is a good example of Newton's First Law of inertia











Aa ball sits motionless on the ground


Ba ball gathers speed as it rolls downhill


Ca ball accelerates as it falls out of the classroom window


Da ball slows down after it is kicked through the grass

Verified Answer :

A good Example of Newton's First Law of Inertia is actually A

Answer: The correct option is A.

Explanation:

Inertia is a state of an object or body to maintain its state. It resists any change in its state.

Newton's first law of inertia: When an objects is in state of motion, it will remain its state of motion or if it is in state of rest then it will remain in rest unless it is acted upon by external motion.

In the given options, a ball sits motionless on the ground is good example of Newton's first law motion. No external force is acting in this case.

In options (B), (C) and (D) , the external force is acting.

Therefore, the correct option is A.
