The acceleration due to gravity on the surface of mars is about one third the acceleration due to gravity on earth’s surface.
the weight of a space probe on the surface of mars is about?
a. one third its weight on earth’s surface.
b. nine times greater than its weight on earth’s surface.
c. three times greater than its weight on earth’s surface.
d. the same as its weight on earth’s surface.

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.
