Friction provides multiple benefits in our daily lives. It is necessary for using tools such as gripping a hammer or turning a screw. Friction also helps to keep clothes in place and prevent them from sliding off. Additionally, friction between furniture legs and the floor prevents sliding and helps maintain stability.
Principles of Friction:
- Frictional Force is Proportional to Normal Force.
- Friction Acts Opposite to the Direction of Motion.
- Friction is Independent of the Area of Contact.
- Static Friction is Greater than Kinetic Friction.
- Friction Depends on the Nature of the Surfaces.
- Friction Produces Heat.
- Friction Can Lead to Wear.
