Question
Which of these affect the force of friction?
Hint:
Friction is a contact force when two surfaces interact.
The correct answer is: Nature of the surface
- Friction is a resistive force, which comes into play when there is a relative motion between two bodies in contact.
- The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.
- Friction is a contact force when two surfaces interact. Hence, so friction depends on the surface of contact as the surface of contact increases the frictional force also increases.

How does friction affect speed?
Friction is the force opposing one solid object's movement over another. Four categories of friction exist fluid friction, rolling friction, sliding friction, and static friction.
¶The frictional force keeps our feet planted on the ground when we walk on or on the floor. As a result, we frequently slip on icy or slippery surfaces because there is less friction.
¶According to scientists, friction is caused by the interactions of tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert force on each other, making it difficult for the surfaces to slip over each other.
