Explanation:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

  1. Friction is a contact force, applied between two surfaces that have relation motion.

  1. Friction always opposes the relative motion by applying a force in opposite direction.

  1. It is a self adjusting force. It first increases with the application of external force and then becomes constant by attaining a maximum possible force.

TYPES OF FRICTION :-

Rolling Friction

  • It is the resistance produced when a rolling body moves over a surface.
  • Rolling friction has a lesser magnitude than sliding friction.
  • Example :- small wheels in the suitcase

Sliding Friction

  • This is the frictional force between two surfaces when one body or object moves or attempts to move over the other.
  • Sliding friction is the moment of force required to retain the state of motion of the moving object at the same speed.
  • Example :- When you apply force to an already moving box to keep it moving on the floor it with the same speed.

Static Friction

  • It is the friction that works between two surfaces which are in contact, but there is no relative movement between them.
  • Static friction is the amount of force applied at the instànt when an object starts moving from its state of rest.
  • Example :- when you push a heavy box on the floor, the force that you apply to start it moving on the floor.
