Which arrow represents the change of state described above?
The diagram shows changes of state between solid,
liquid, and gas. The atoms of a substance gain energy
during a change of state. Before the change, the
atoms are close together and cannot slide past one
another After the change the substance can fill its
container

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.
