3objects that have gravitational potential energy?

When an object is above the Earth's surface it has gravitational potential energy (GPE). The amount of GPE an object has depends on its mass and its height above the Earth's surface.
The weight of an object is the size of the force of gravity pulling the object down. When an object falls it transfers GPE to KE (kinetic energy).

The water in the tank above the buildings
The fruits on the tree
Something like a cup or a book or a laptop on the table

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
