What is the Frictional Force?

Question

Define the Frictional Force? Or, What do You Mean by the Frictional Force?

Answer 1

Frictional Force : It is the force exerted by a surface when an object moves across the surface.

There are two types of frictional forces ;

1. Kinetic friction
2. Static fraction

• Frictional force can also be defined as the force, which opposes the motion of an object.
• It is also known as the constant force.
• The frictional force also depends on the nature of the surface and degree to which they are pressed together.
• The maximum amount of frictional force is calculated by using the relation ;

Force = Coefficient of friction × Normal force.
