Which statement is true about the gravitational force?
a.
it acts on all objects all of the time.
b.
it only acts on objects that are in contact.
c.
it only acts on objects that are moving apart.
d.
it only acts on objects that are close to each other.

iron would move it is magnetic there is a mag field around the current in the wire

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.
