Answer:

Kinetic and Potential Energy Absorbed by Brake

Brakes are used to slow or stop a moving vehicle or machine by absorbing its kinetic energy. However, the energy absorbed by brakes may also include potential energy, depending on the situation. Therefore, option B is the correct answer.

Kinetic Energy

Kinetic energy is the energy possessed by a moving object due to its motion. When a vehicle or machine is in motion, it possesses kinetic energy. When brakes are applied, they convert this kinetic energy into heat energy, which is dissipated into the atmosphere. The amount of kinetic energy absorbed by brakes depends on the mass, speed, and stopping distance of the moving object.

Potential Energy

Potential energy is the energy possessed by an object due to its position or configuration. For example, a vehicle or machine at a height possesses potential energy due to its gravitational field. When brakes are applied, they convert this potential energy into heat energy, which is dissipated into the atmosphere. The amount of potential energy absorbed by brakes depends on the height, weight, and stopping distance of the moving object.

Conclusion

In conclusion, the energy absorbed by brakes may include both kinetic and potential energy, depending on the situation. Therefore, option B is the correct answer. The amount of energy absorbed by brakes depends on various factors, such as the mass, speed, height, weight, and stopping distance of the moving object.
