Question

In order for an object to have kinetic energy it must have a mass and a ?

Answer 1

Answer:

Velocity

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.
