How does the use of car brakes reduce friction?
When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.
Where can friction can be both useful and unwanted?
Friction can be useful in car brakes to slow down or stop a vehicle safely. On the other hand, friction can be unwanted between moving parts in machinery, as it can cause wear and reduce efficiency.
What friction slows down a car?
The main sources of friction that slow down a car are rolling resistance between the tires and the road, air resistance from the drag force due to the motion of the car through the air, and brake friction when the brakes are applied to stop the car. All of these friction forces act to oppose the motion of the car and reduce its speed.
How does friction affect forward motion Give and example?
Friction opposes motion by creating resistance between surfaces in contact. In the context of forward motion, friction can reduce the speed of an object. For example, when a car applies brakes, the friction between the brake pads and the rotors slows down the car by converting its kinetic energy into heat energy.
What mechanical motion principle do the brakes in a car or on a bicycle use?
The brakes in a car or bicycle use the mechanical motion principle of friction to slow down or stop the vehicle. When the brake is applied, friction is generated between the brake pads and the rotor (for disc brakes) or the wheel rim (for rim brakes), converting kinetic energy into heat and bringing the vehicle to a stop.
How does the use of car brakes reduce friction?
When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.
Why do car brakes get hot they are new brakes?
Because brakes create friction, and heat is a byproduct of friction.
