If a 10 kg object has 200 J of gravitational potential energy, how high was has it been lifted above the ground?

Potential energy is possessed by the body while at rest while the body in motion possesses kinetic energy.

Potential energy is given by mgh where m is the mass of the body, g is the gravitational acceleration (9.8m/s^2) and h is the height.

Therefore, 200J = 10 * 9.8 * h

h = 200/98

h = 2.041 m
