the gravitational field between earth and the apple
An apple hanging from a tree has gravitational potential energy...anything which could fall to the ground has gravitational potential energy
When the CG of an object is raised, gravitational potential energy increases due to a higher positioning from the ground, and therefore a higher "potential" to fall.
As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.
Well gravitational potential energy is potential energy that depends on the height of an object so an object would have gravitational potential energy when ever it's of the ground or at a high height (it doesn't have to be very high) for example if you lift up a ball it has the potential to fall or if your climbing a mountain you have gravitational potential energy.
If using the formula U=mgh, then potential energy increases when the height above the ground increases.

Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height
If using the formula U=mgh, then potential energy increases when the height above the ground increases.
Potential Energy
Potential
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
potential energy it is directly proportional to height of object above ground
If an object is above ground level, it has positive gravitational potential energy. (This assumes you define ground level to be zero - actually, you can define any level to be zero.)
As we lift a body of mass m from ground level to a height h, then work performed will be mgh which is equal to the difference in gravitational potential energy at the ground level and at that height.
