the altitude
The height of an object above a reference point is its potential energy with reference to that point.
Yes, that is one meaning of "reference point", although the reference point need not be an object, but may simply be a location.
No because enable to see if the object is moving it needs a reference point other than itself.
To support you in specifying how the reference point is placed and how the object is moved away from the reference point.
a reference point i just had that test a while ago!

Basically yes. There are different types of energy; for example: * Kinetic energy: Every moving object has kinetic energy. Whether an object is moving or not depends on the reference frame you choose. * Gravitational potential energy: Once again, you need to choose a reference point - or actually, a reference height in this case. Anything above the chosen reference height will have positive potential energy; anything below it, negative potential energy. * Heat energy: Since you can't cool any object to absolute zero, any object will have at least some heat energy.
Its position, relative to the point of reference.
