Question

Why does a body rolling on the surface of the Earth come to the state of rest after some time?

• A. it has mass
• B. it experiences friction
• C. it has inertia of rest.
• D. All of the above

Answer 1

The correct option is B

it experiences friction

Explanation for correct answer: Option (B)

1. Friction is the force acting between two surfaces in contact, or the force of a medium acting on a moving object (e.g., air on aircraft) to resist the relative motion.
2. Frictional forces may also exist between surfaces when there is no relative motion.
3. Frictional forces arise due to molecular interactions.
4. Force of friction always opposes relative motion.
5. Due to friction on the surface of the Earth, a body comes to a state of rest after some time.

Hence,body rolling on the surface of the Earth come to the state of rest after some time due to friction.
