Question 8
F

A crate of mass 20 kg is lifted 3.0 m onto a shelf.

Gravitational field strength = 10 N/kg.

Use the equation: gravitational potential energy=mass×gravitational field strength×height\text{gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{height}gravitational potential energy=mass×gravitational field strength×height

What is the increase in the gravitational potential energy of the crate?
