Find the potential energy of a body weighing 50g, lifted to a height of 2m from the Earth’s surface.

m = 50 g = 0.05 kg.

g = 9.8 m / s2.

h = 2 m.

Ep -?

The potential energy of a body Ep of mass m, which was raised to a height h above the earth’s surface, is determined by the formula: Ep = m * g * h, where g is the acceleration of gravity.

Ep = 0.05 kg * 9.8 m / s2 * 2 m = 0.98 J.

The potential energy of the body En shows what kind of mechanical work A the body can perform.

Answer: the body has a potential energy of Ep = 0.98 J.
