Question

Which one of these is a correct sentence?

A) A normal force doesn't affect the frictional force.

B) The area of contact doesn't affect the frictional force.

C) A normal force affects the frictional force.

D) The area of contact affects the frictional force.

Answer 1

The normal force affects the frictional force.As stated in the reference materials, the force of friction depends on two factors: the coefficient of friction and the normal force. So, the normal force does indeed affect the frictional force.

Step-by-step explanation:

The correct sentence is option C) A normal force affects the frictional force.

The normal force is the force exerted by a surface that pushes on an object in response to gravity pulling the object down. Friction, on the other hand, is a contact force that opposes the motion or attempted motion between two systems.

As stated in the reference materials, the force of friction depends on two factors: the coefficient of friction and the normal force. So, the normal force does indeed affect the frictional force.
