A load of mass 5kg is raised through a height of 2m. (g=10mls)

The gain in gravitational potential energy of the mass = 100 kg m^2 / s^2.

Explanation:

Gravitational potential energy is an energy in which an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the Earth's surface where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

The formula for the gravitational potential energy is the product of mass, gravity, and height.

GPE = m * g * h

where m represents mass in kg,

g represents the gravity,

h represents the height.

GPE = 5 * 10 * 2 = 100 kg m^2 / s^2.
