What is the potential energy of the body on the table relative to the ground, if its mass is 500g

What is the potential energy of the body on the table relative to the ground, if its mass is 500g, the height of the table is 1m?

m = 500 g = 0.5 kg.

g = 10 N / kg.

h = 1 m.

Ep -?

The potential energy of a body Еп of mass m, which is located at a distance h from the earth’s surface, is determined by the formula: Еп = m * g * h, where g is the acceleration of gravity.

Since the height of the table above the surface of the earth is h, then the body that is on it also has a height of h.

Ep = 0.5 kg * 10 N / kg * 1 m = 5 J.

This means that the body that lies on the table can perform mechanical work A = 5 J.

Answer: the potential energy of the body on the table is En = 5 J.
