A small model glider has a mass of 0.075 kg.

During a flight test, the glider descends through a vertical height ( $Δh\Delta h$ ) of 40.0 cm.

The gravitational field strength, $g$ , is 10 N/kg.

Calculate the change in the gravitational potential energy ( $ΔGPE\Delta \text{GPE}$ ) of the glider.

Use the equation:

\Delta \text{GPE} = m \times g \times \Delta h
