Determine the potential energy of a body weighing 200 kg, lifted to a height of 500 m.

m = 200 kg.

h = 500 m.

g = 10 N / kg.

Ep -?

The potential energy of a body En of mass m, which is at a height h above the Earth’s surface, is determined by the formula: En = m * g * h. Where g is the acceleration due to gravity, the value of which within the Earth’s surface can be approximately considered g = 10 N / kg.

Ep = 200 kg * 10 N / kg * 500 m = 1,000,000 J = 1 * 10 ^ 6 J = 1 MJ.

Potential energy En is a measure of mechanical work A
: En = A. This body is capable of performing mechanical work A = 1 MJ.

Answer: the potential energy of the body is En = 1 MJ.
