Question

At what height does a 1000-kg mass have a potential energy of 1J relative to the ground? Be sure to show all work to support your answer.

Answer 1

Potential energy = (mass) x (gravity) x (height)

1 joule = (1,000 kg) x (9.8 m/s²) x (height)

Height = 1 joule / (9,800 newtons)

= 1/9800 meter

= 0.000102 meter

= 0.102 millimeter (rounded)
