-- If the car is a hybrid or all-electric, then braking converts some of its kinetic energy
into some heat, which is dissipated into the air, and some electrical energy, which is
put back into the batteries.
-- If the car is the classic internal combustion type, then braking converts some of
its kinetic energy to all heat, which is dissipated into the air, and which can burn up
the brakes if it goes on for too long.
Trick question--The answer is none. Indeed, energy in the form of heat is produced by the car stopping. But no energy is required to stop it. The brake pads, and drums or discs absorb energy and get hot.

Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
((.5 * 960) * ((101 * 1 000 * 60 * 60)^2)) * 0.000239005736 = 1.5166917 × 1016 1/2 M V^2= kinetic energy times conversion from joules to kilocalories.
Thee Car Stopsss -_-
A common example of conversion of chemical energy to mechanical energy is in a car engine where the combustion of fuel releases energy that is then converted into mechanical energy to move the vehicle.
When a man fills his car with gas, he expects a conversion of chemical energy into mechanical energy. The gasoline contains stored chemical energy, which is released during combustion in the engine. This combustion process converts the chemical energy into thermal energy, which is then transformed into mechanical energy to power the car's movement.
When a solar-powered car is moving, the energy conversion involved is solar energy being converted into electrical energy by solar panels, which is then stored in a battery. The electrical energy stored in the battery is then converted into mechanical energy by the motor to propel the car forward.
Three conversions in energy transformation may include chemical energy in gasoline converting to thermal energy in a car engine, then to mechanical energy to move the car, and finally to kinetic energy as the car moves.
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
No. The driver of the car that threw the rock has no way of knowing that his car caused the accident.
The sound energy produced from a car coming to a screeching halt is not a useful form of energy, as it represents energy lost in the conversion process. In this case, the kinetic energy of the car is being converted into both heat and sound energy, which are typically considered wasted energy.
Try to put your car on the parking breakes.
Chemical Potential Energy to kinetic energu
The energy used to move the toy car when you push it is mechanical energy, specifically kinetic energy. When you apply force to the car, you transfer energy from your muscles to the car, causing it to accelerate and move. This energy conversion occurs as the potential energy stored in your muscles is released during the push.
When energy is used, it is converted from one form to another. For example, when a car runs, the chemical energy in the gasoline is converted to kinetic energy to move the car. Some of the energy is dissipated as heat during the conversion process.
