alleryMechanical energy is:
AThe energy that is released during any mechanical work
BThe energy that is equal to the rate of doing work
CThe energy absorbed during the movement of a body
DThe sum of kinetic energy and potential energy of an object
Answer & Solution
Correct answer: D. The sum of kinetic energy and potential energy of an object
1. Mechanical energy is the energy possessed by an object due to its motion and its position.
2. Energy of motion is kinetic energy; energy of position is potential energy.
3. Hence mechanical energy is the sum of kinetic and potential energy.
