Best Answer

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.
