Newton's law of universal gravitation​

Explanation:

The gravitational force exerted on an object by another is equal to that which the other exerts on it.

F=GMm/r²

G=6.67x10-¹¹Nm²/Kg²

r= 80cm=0.8m

F= [6.67x10-¹¹ x 70 x 55]/0.8²

F= 4 x 10^-7N.

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.
