A wooden block has a mass of 0.25 kg.
Calculate the change in gravitational potential energy when the block is lifted through a vertical height of 2.4 m.
gravitational field strength, g=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg
Use the equation:
ΔGPE=m×g×Δh \Delta \text{GPE} = m \times g \times \Delta h ΔGPE=m×g×Δh
