The formula for potential energy is, P. E = mgh joules

The formula for kinetic energy is K. E = ½ mv² joules

Explanation:

The total mechanical energy of the system is the sum of the K. E and the P. E The potential energy of the system is associated with the position of the object from the ground. The formula for potential energy is,

P. E = mgh joules

The kinetic energy of the object is associated with the velocity of the object. The formula for kinetic energy is,

K. E = ½ mv² joules

From the above equation, it is clear that the P. E is dependent on the mass and acceleration due to gravity. The P. E is the product of mass, acceleration due to gravity and height of the object from the ground. Whereas the K. E is dependent on the mass and the velocity of the object. The kinetic energy does not depend on the acceleration due to gravity.
