80 J is potential energy.
What is potential energy?
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
According to question,
Gravitational field strength = 10 N/kg
Mass (m) = 4kg
Height (h) = 2m
By the formula of potential energy:
Ep = mgh
Ep = (4 kg) (10 m/s²) (2 m)
Ep = 80 J
Therefore,
80 J is potential energy of bowling ball.
