Question 4

A parcel of mass 4 kg is lifted vertically onto a shelf 1.8 m high.

Calculate the gain in gravitational potential energy of the parcel.

Assume gravitational field strength = 10 N/kg.

Use the equation:

potential energy=mass×height×gravitational field strength \text{potential energy} = \text{mass} \times \text{height} \times \text{gravitational field strength} potential energy=mass×height×gravitational field strength
