Question

At what height from the surface of earth the gravitational potential and the value of g are

Answer 1

Gravitational Potential Energy near the Earth

On Earth, the gravitational potential energy of an object (Ug) depends on the mass of the object (m), the gravitational acceleration on Earth (g = 9.8 m/s2), and how high up the object is raised (h). In this case, the surface of the Earth is considered to be the point where gravitational potential energy is zero. Therefore, as you move the object farther and farther away from the Earth, its potential energy increases!
