A small model glider has a mass of 0.075 kg.
During a flight test, the glider descends through a vertical height (Δh\Delta hΔh) of 40.0 cm.
The gravitational field strength, ggg, is 10 N/kg.
Calculate the change in the gravitational potential energy (ΔGPE\Delta \text{GPE}ΔGPE) of the glider.
Use the equation:
ΔGPE=m×g×Δh \Delta \text{GPE} = m \times g \times \Delta h ΔGPE=m×g×Δh57 exam-style questions on Edexcel GCSE Physics 8.1 Energy transfers and work. Each one has a worked solution and a mark scheme showing where the marks go.
