True or false: 1.Gravity is the weakest universal force, but it is the most effective over long distances.

True or false:

2.An artificial satellite in a low orbit will slow down and lose altitude due to the pull of Earth's gravity.

True or false:

3.Electromagnetic force is associated with charged particles.

False

True

Explanation:

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.
