Question

What units are used for gravitational potential energy ?

Answer 1

Explanation:

1. gravitational potential energy is measured in joules (j).
2. mass is measured in kilograms (kg)
3. height is measured in metres (m)
4. gravitational field strength(g) is measured in Newton's per kilogram (N/kg).

hope this helps you dear friend!!

Answer 2

Answer:

The units of gravitational potential energy and kinetic energy are kg m2 / s2.

Explanation:

The potential energy that a massive object has in relation to another massive object as a result of gravity is called gravitational potential energy. It is the potential energy in the gravitational field that is released when the objects fall toward one another and is transformed into kinetic energy. When two things are separated by a greater distance, the potential energy of gravity rises.

An object's position in a gravitational field gives it energy known as gravitational potential energy. An object close to Earth's surface, whose gravitational acceleration can be assumed to be constant at approximately 9.8 m/s2, is the most common application for gravitational potential energy. The potential energy at a height h above that point is equal to the work required to lift the object to that height with no net change in kinetic energy because the zero of gravitational potential energy can be chosen at any point, just like the zero of a coordinate system. The gravitational potential energy of the object is proportional to its weight divided by the height at which it is lifted, as the force required to lift it is proportional to its weight.
