An automated research pod of mass 12.5 kg is hoisted vertically up a meteorological tower to a height of 32 m.
Calculate the increase in gravitational potential energy of the pod.
Use the equation:
gravitational potential energy=mass×gravitational field strength×height \text{gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{height} gravitational potential energy=mass×gravitational field strength×heightGravitational field strength, g=9.8 N/kgg = 9.8\ \text{N/kg}g=9.8 N/kg.
