A person driving a car applies the brakes. This produces friction, which stops the car. Into which type of energy is the mechanical energy of the car converted

Heat energy

Explanation:

Energy is the ability to do work or perform a task. Energy exists in different forms depending on the source. As mentioned in the question, the moving car uses kinetic energy, which is a type of mechanical energy an object possesses in motion.

However, when the driver of the car applies the brakes, friction is produced between the tyres of the car and the ground in order to stop the car. Friction is a force that opposes two objects in motion. When friction is applied, heat is produced. Hence, when the moving car stops due to the friction produces, heat is released in the process.

Therefore, it can be said that the mechanical energy (kinetic energy) of that car was converted to heat energy when it stopped as a result of friction.

When a car stops it converts its kinetic energy into heat energy as the breaks are applied the engine gets heated along with breaks and tiers.
