Find the potential energy of a body weighing 500 g raised to a height of 2 m from the earth’s surface.

Potential energy (in the gravitational field of the Earth) is calculated by the formula:
Ep = mgh, where m is the body mass (m = 500 g = 0.5 kg), g is the acceleration of gravity (we take g = 10 m / s ^ 2), h is the body height above the zero level (h = 2 m ).
Let’s calculate the potential energy of the body:
Ep = mgh = 0.5 * 10 * 2 = 10 J.
Answer: The potential energy of the body is 10 J.
