Dynamic friction as compared to static friction is

Right Answer is:

Greater

SOLUTION

Friction: Friction is an opposing force that comes into play when the body is actually moving (slide or roll) or even tries to move over the surface of another body.

  • Static friction(Fs): The opposing force that is active when the body tends to move over the surface, but the actual motion is yet not started.
  • Kinetic friction(Fk): Kinetic or dynamic force is an opposing force that is active when the body is actually moving on another surface.

The kinetic frictional force is less than the maximum static frictional force for any given pair of surfaces with the same normal force.
