A toy drone has a mass of 0.32 kg.
Calculate the increase in gravitational potential energy of the drone when it climbs vertically through a height of 4.5 m.
Gravitational field strength, g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg.
Use the equation:
ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp=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.
