Relative to the ground below, how many joules of potential energy does a 1000-kg boulder have at the top of a 5-m ledge?

Data given:

mass=1000kg

h=5m

Data needed:

Potential Energy=Ep

Formula needed:

Ep=mgh

Solution:

Ep=1000kg×9.81m/s²×5m

Ep=49050J

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
