Question

What are the factors that affect the friction ?

Answer 1

1. Force is a push or pull.
2. Forces can be classified into two, contact and non-contact forces.
3. Friction force is a contact force.
4. Contact forces are those forces that are physically in contact with each other.
5. The factors that affect the frictional force are:

5.1 Nature of bodies: When roughness increases frictional force also increases.

5.2 Weight of the bodies: When weight increases frictional force also increases.

5.3 Area of contact: When the area of contact increases, the frictional force also increases.
