What is the main difference between the formulas for kinetic energy (KE) and gravitational potential energy (PE)?
Kinetic energy is a energy that a body possesses by virtue of being in motion.
And gravitational potential energy is where m is the mass in kilograms, g is the acceleration due to gravity.
Answer:
A body possess kinetic energy by virtue of its motion. It is given by:
\(K.E. = \frac{1}{2}mv^2\)
where m is the mass and v is the speed.
A body possess potential energy by virtue of its position.
Gravitational potential energy is given by:
G.P.E. = m g h
where m is the mass, g is the acceleration due to gravity and h is the height.
The sum of kinetic energy and potential energy is known as mechanical energy.
