Types of Friction :
Friction is the force that opposes the motion of objects in contact.
There are primarily four types of friction:
Static Friction:
Description: Acts on objects at rest, preventing them from moving.
Example: The force that keeps a book on a table until you push it.
Kinetic Friction:
Description: Acts on moving objects, resisting their motion.
Example: The force that slows down a sliding sled on snow or a moving car on a road.
Rolling Friction:
Description: Occurs between a rolling object and the surface it rolls on.
Example: The force that slows down a rolling ball on the ground.
Fluid Friction (also called Viscous Friction):
Description: Acts on objects moving through a fluid (liquid or gas).
Example: The resistance a fish encounters while swimming in water or the air resistance experienced by a moving car.
