Why do objects at high elevations have more potential energy than objects at low elevations?

• Because the thinner air at higher elevations means objects have a greater potential to move very fast

• Because objects at high elevations are closer to the sun, which is the source of all energy on earth

• Because objects at high elevations tend to move slower than objects at low elevations

• Because gravity gives objects at high elevations the potential to fall much further
