Question

The force which acts at the surface of contact, when one body is made to slide upon another body is known as:

• A. Frictional force
• B. resistive force
• C. mechanical force
• D. none of these

Answer 1

The correct option is A

Frictional force

Explanation:

1. The force which acts at the surface of contact, when one body is made to slide upon another body is known as frictional force.
2. The frictional force always opposes the motion.
3. The direction of frictional force is always opposite to the direction of motion.

Hence, the correct option: (A)Frictional force
