Gravitational potential and gravitational potential energy. are ideas used to calculate the forces and energy required to move an object within a gravitational field.
When we calculate changes in gravitational potential energy over short distances near to the earth we use the simple equation “F = mgh”. However over larger distances the value of g varies. The video explains why and how changes in the gravitational field strength can be taken into account.  Notes and many more video lessons available here: https://www.fizzics.org/free-physics-... https://www.fizzics.org/gravitational...
