Study Notes
Advantages of Friction
- Friction enables walking or moving on any surface, as it prevents slipping and allows for applied force against the ground.
- Without friction, daily routine activities would be severely affected.
- Friction allows for movement on various surfaces, such as walking on ice, but it's more challenging due to lower friction.
- Friction between the road and tyres enables automobiles like bikes, cars, buses, and trucks to move.
Holding Objects
- Friction enables us to hold things with our hands, preventing them from slipping out.
Reducing Speed and Stopping Objects
- Friction helps reduce the speed or stop moving objects, commonly utilized in vehicle brakes.
- The mechanism of brakes in vehicles like two-wheelers, cars, etc. relies on friction between the wheel and brake pads.
- Over time, frequent use of brakes causes brake pads to wear out due to friction.
