Answer:
Velocity
Step-by-step explanation:
- The mechanical energy of the body is defined as the sum of the potential energy and kinetic energy.
E = P.E + K.E
- The potential energy of a body is due to the height from the surface of the earth.
P.E = mgh
- The kinetic energy of the is possessed by the body due to the virtue of its motion,
K.E = ½ mv²
- If there is no velocity associated with the body, there is no K.E in the body.
