How do the mass and height of an object affect the gravitational potential

energy?

The bigger the mass and the higher the height of the object above earth's surface, the bigger the potential energy. The potential energy can be evaluated using the formula below;

P. E. = m*g*h, where

m = mass in kilograms,

g = the acceleration due to gravity (9.8 m / s² at the surface of the earth), and

h = height in meters.

From the formula, it is clear that increasing mass, gravity or/and height will give an increased potential energy
