Explanation:

The energy absorbed by brakes is kinetic or potential energy. This is because brakes are used to slow down or stop a moving object, such as a vehicle. In order to do this, the brakes convert the kinetic energy of the moving object into another form of energy, such as heat or potential energy.



Brakes and Kinetic Energy:
When a vehicle is in motion, it possesses kinetic energy due to its speed and mass. The brakes exert a force on the moving parts of the vehicle, such as the wheels or rotors, which causes them to slow down or stop. This force applied by the brakes converts the kinetic energy of the moving parts into other forms of energy.



Conversion of Kinetic Energy:
When the brakes are applied, the kinetic energy of the moving parts is converted into heat energy. This is due to the friction between the brake pads and the rotors or wheels. The heat generated during this process is dissipated into the surrounding environment.



Potential Energy:
In some cases, the energy absorbed by the brakes may also be converted into potential energy. This can occur in situations where the brakes are used to hold a stationary object in place, such as a parked car on a slope. In this case, the brakes are engaged to prevent the car from rolling down the slope. The potential energy of the car is stored in the brakes, as they are holding the car in a higher position against the force of gravity.



Conclusion:
In conclusion, the energy absorbed by brakes is primarily kinetic energy as it is used to slow down or stop a moving object. The kinetic energy is converted into heat energy through friction between the brake pads and the moving parts. In some cases, the energy may also be converted into potential energy when the brakes are used to hold a stationary object in place.
