Figure 1 shows a motorized hoist lifting a crate of equipment at a building site.

A diagram showing a motorized hoist lifting a crate vertically off the ground to a height of 3.2 m. The crate has a mass labels of 65 kg.

The crate has a mass of 65 kg.

The hoist lifts the crate through a vertical height of 3.2 m.

The gravitational field strength, g=10 N/kgg = 10 \text{ N/kg}g=10 N/kg.

Calculate the change in the gravitational potential energy of the crate.

Use the equation:

ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp​=m×g×Δh
