Object a attracts object b with a gravitational force of 10 newtons from a given distance. if the distance between the two objects is doubled,
what is the new force of attraction between them?
a
2.5 newtons
b. 5 newtons
c. 20 newtons
od. 100 newtons

a and b sometimes have a positive value

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.
