A crane lifts a crate vertically upwards from the ground to the top of a building platform.
The platform is 15 m vertically above the ground.
The crate has a mass of 120 kg.
Calculate the increase in gravitational potential energy of the crate.
gravitational field strength, g=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg
