Mechanical Energy
Mechanical energy is the
energy which is possessed by an object due to its motion or due to its
position. Mechanical energy can be either kinetic energy (energy of motion)
or potential energy (stored energy of position). Objects have mechanical
energy if they are in motion and/or if they are at some position relative to
a zero potential energy position.
For example:
A moving car possesses
mechanical energy due to its motion (Kinetic energy).
A book on the
top shelf of a locker possesses mechanical energy due to its vertical position
above the ground (gravitational potential energy).
