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)
