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.
What mechanical motion principle do the brakes in a car or a bicycle use?
The brakes in a car or a bicycle use the principle of friction to convert the kinetic energy of the moving vehicle into heat energy. When the brake pads press against the rotating wheels, friction is created, causing the vehicle to slow down or stop.
Which type of energy is the mechanical energy of the car converted?
Most of it will be converted to heat, via friction.
When a moving train stops kinetic energy is changed to which kind of energy?
Heat, from the friction in the brakes.
What are five examples that illustrate mechanical energy being converted to thermal energy?
Friction between moving parts in a machine can convert mechanical energy into thermal energy. When brakes are applied in a moving vehicle, mechanical energy is converted to thermal energy due to friction between the brake pads and the wheels. The act of rubbing your hands together generates heat by converting mechanical energy into thermal energy. Electric heaters convert electrical energy (which is ultimately derived from mechanical energy in power plants) into thermal energy, which in turn heats up a room. When a ball bounces repeatedly on the ground, mechanical energy is gradually dissipated as thermal energy due to internal friction within the ball and between the ball and the ground.

What part of a bicycle is a useful friction?
The brakes! And the tires (no friction = no traction).
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
A car slams on its brakes producing friction between the tires and the road. Into which type of energy is the mechanical energy of the car converted?
thermal energy.
Why do bicycles have brakes?
Brakes help a bicycle to stop, of course --- but do you know why? it's because brakes use friction. When you squeeze the brakes, rubber blocks press against the wheels. The friction between the blocks and the wheels slow your bicycle down.
Which type of energy is the mechanical energy of the car converted?
Most of it will be converted to heat, via friction.
What causes some mechanical energy to change to thermal energy?
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
Parts of a bicycle where friction can be maximised?
The brakes and the tire treads.
What do brakes do?
A vehicals brakes convert kinetic energy into thermal energy through friction and dissipate the thermal energy into the atmosphere
Where do you find friction in brakes of a bicycle brake?
A bicycle has high friction at the brakes, first and foremost. Then at places where the rider holds on to the bike, Grips and pedals. Between tires and road.
When a moving train stops kinetic energy is changed to which kind of energy?
Heat, from the friction in the brakes.
