Friction offers multiple advantages, as it provides the needed traction for acceleration, deceleration, and turning between tires and the road; it also slows down and stops the vehicle through friction in the brake pads and disc. Additionally, it aids in maintaining control of the vehicle, especially during sharp turns and on slippery roads.
Different Applications of Friction:
Applications of Contact Friction
- Climbing a ladder, writing with a pencil.
- Braking a car, sharpening a knife.
- Driving a car, rolling a suitcase
Applications of Fluid Friction
- Pumping oil, mixing liquids in a blender.
- Designing aerodynamics of vehicles, using wind turbines.
Applications of Internal Friction
- Earthquake-resistant buildings, tuning a guitar.
- Shock absorbers in cars, damping in mechanical clocks.
Applications of Surface friction
- Walking on a rough surface, using sandpaper.
- Machinery lubrication, reducing wear in gears.
