Question

A. Write 'T' for True and 'F' for False for each of the following statement.
1. The maximum force of friction which operates when one body slides
over another is called sliding friction.
2. Friction is due to the roughness of the two surfaces in contact with each other
3. Force of friction depends on the area of the surfaces in contact.
4. The application of brakes to stop a bicycle is due to the friction between
the brake-lining and the rim.

B. Write one word for each of the following.
1. Force that acts along the surfaces of contact between two bodies.
2. The property which opposes the relative motion between two
bodies in contact.
