The kinetic energy and the potential energy of an object are called __________.
Hence, the kinetic energy and the potential energy of an object are called mechanical energy.
An object is falling freely from a height x. After it has fallen a height x2, it will possess :
(a) only potential energy
(b) only kinetic energy
(c) half potential and half kinetic energy
(d) less potential and more kinetic energy
The sum of the kinetic and potential energy of a body is called its ____________ energy.
A falling object has potential as well as kinetic energy.
