Two pulleys with different radii are attached to each other so that they rotate together about a horizontal axis through their common center. There is negligible friction in the axel. Object 1 hangs from a light string wrapped around the larger pulley, while object 2 hands from another light string wrapped around the smaller pulley, as shown in the figure above.

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.
