Radha is moving her bike with its brakes on. In this case Correct Answer rolling friction is converted into sliding friction

CONCEPT:

  • Frictional force: It is a type of contact force.
  • Contact forces: It arises when two bodies are in contact with some other object: solid or liquid
    • When two bodies are in contact mutual force arise due to newton's third law of motion.
    • The component of contact force normal to the surface is called normal reaction and the component parallel to the surface is called friction.
  • Rolling friction: When an object is rolled over the surface of another object an opposing force comes into action. This opposing force is called rolling friction.
    • The rolling body in contact with the plane gets slightly compressed and the motion relative to the plane is zero.
    • The net effect is that component of contact force parallel to the surface opposes the motion.

Additional Information

  • Rolling friction is much smaller than static or sliding friction.
