Mechanical energy of an object is the sum of its Potential Energy and _?
Correct answer: C. Kinetic Energy
- A. Electrical Energy
- B. Thermal Energy
- C. Kinetic Energy
- D. All of these
Explanation
Mechanical energy is the energy associated with the motion and position of an object. It is the sum of potential energy (PE) and kinetic energy (KE).Potential Energy (PE): Energy possessed by an object due to its position or configuration. For example, a book held above the ground has potential energy due to its height.Kinetic Energy (KE): Energy possessed by an object due to its motion. For example, a moving car has kinetic energy

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
