Kurt, a junior high school student, lifts a 5-kg book from the floor into a cabinet 12.0m high. With reference to the floor, how much potential energy does the book acquire?

Given:

  • Mass (m) = 5 kg
  • Height (h) = 12.0 m
  • Potential energy (PE) = ?

Formula: PE = mgh

Whereas:

  • m = mass
  • g = acceleration due to gravity which is always constant. The value for g is 9.8 m/s²
  • h = height

Solution:

PE = 5 kg (9.8 m/s²) (12.0 m)

PE = 5kg (117.6 m²/s²)

PE = 588 kg•m²/s²

(Potential energy has a SI unit of Joules (J), 1 J = 1 kg•m²/s²)

PE = 588 J
