Because the moon rotates once for each revolution around earth,
a. you see some phases more than others.
b. a different side of the moon faces earth each day.
c. you never see the far side of the moon from earth.
d. the far side of the moon is visible only during the full moon phase.

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.
