Question

list out the material required to verify the experiment that friction does not depend on contact area

Answer 1

Answer:

If the surface area is rough, the frictional coefficient of the surface will be higher, requiring more force to slide and increasing friction.

Explanation:

• The co-efficient of friction between two surfaces is reduced when the surface area is smooth.
• Thus, friction is determined by the characteristics of the surface with which it comes into contact.
