The work done on the rock when it reaches maximum height is by gravitational force is 9.8mh (J).

Work done on the rock by gravitational force

The work done on the rock by the gravitational force is determined  as follows;

P.E = mgh

where;

  • m is mass of the rock
  • h is the maximum height reached by the rock
  • g is acceleration due to gravity

P.E = m x 9.8 x h(max)

P.E = 9.8mh (J)
