What type of energy transforms when a ball rolling off a table top and bouncing on floor until it stops?
The potential energy of the ball (due to its position on the table) transforms into kinetic energy as it rolls off the table and falls. When the ball hits the floor, some of the kinetic energy transforms into elastic potential energy as the ball compresses and then rebounds. Finally, friction and air resistance gradually dissipate the ball's kinetic energy into thermal energy, causing it to stop.
Energy transformation in automobile brakes?
When you step on the brakes in a car, kinetic energy from your car's motion is converted into heat energy through friction between the brake pads and the brake rotors. This heat energy is dissipated into the air, slowing down the car. The transformation from kinetic energy to heat energy helps bring the car to a stop.
What happens to the kinetic energy of a car when it is braked to a stop?
The energy is generally converted to unusable energy, mainly heat. It is also possible to design special brakes that recover part of the kinetic energy, for example storing it in a battery, in a flywheel, etc., but this is not common.
What kind of energy transformation takes place when your push the brakes and stop the car?
When you push the brakes and stop the car, the kinetic energy of the moving car is transformed into heat energy through friction between the brake pads and the wheels. This process reduces the car's kinetic energy, bringing it to a stop.
Do car brakes reduce friction?
No, car brakes actually increase friction in order to slow down or stop the vehicle. When the brakes are applied, they create friction between the brake pads and the brake rotors, converting the kinetic energy of the moving vehicle into heat energy that dissipates, causing the vehicle to slow down.
How do brakes stop a car?
Friction converts kinetic energy into heat energy.
What type of energy occurs when you hit the brakes on a bike?
i think it is kinetic energy to thermal energy.

What kind of energy in car engine?
Chemical energy is being converted to thermal energy which is then converted to mechanical energy and finally to kinetic energy which moves the car. Kinetic energy is then converted to thermal energy in the brakes to stop the car.
When a vehicle is slowing down what changes its momentum and kinetic energy as force of brakes is an internal force?
When a vehicle is slowing down, the external force of friction between the brakes and the wheels is what changes its momentum and kinetic energy. This force works against the vehicle's motion, transferring kinetic energy into heat and bringing the vehicle to a stop. The force of the brakes is an internal force that generates friction to slow down the vehicle.

What is the science behind breaks?
The science behind BRAKES is that you use friction to convert kinetic (moving) energy into heat energy to stop a vehicle.
What kind of energy stops a roller coaster car?
A roller coaster car is ultimately stopped by frictional energy, which transforms the car's kinetic energy into heat as it moves against the track and air resistance. Additionally, brakes may be applied to further reduce the car's speed and bring it to a complete stop. Gravitational potential energy also plays a role as the car descends, converting to kinetic energy and eventually dissipating through these forces.

A 735 kg car moving at 20 ms brakes to a stop The brakes contain about 15 kg of iron which absorbs the energy What is the increase in temperature of the brakes?
To find the increase in temperature of the brakes, you need to calculate the total kinetic energy of the car before braking and then determine the amount of energy absorbed by the brakes during braking. Using the equation for kinetic energy (0.5 x mass x velocity^2) for the car before braking and equating it to the energy absorbed by the brakes, you can then find the increase in the temperature of the brakes using the specific heat capacity of iron.
