How is the position of an object related its potential energy?
The height of an object above a reference point is its potential energy with reference to that point.
An object that has NO kinetic energy must be?
An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
Is it possible for a system to have negative potential energy?
Yes. Potential energy can't be specified in absolute terms; you have to arbitrarily define a reference point. For the case of gravitation, any object below the reference point would have negative potential energy. What matters is not the number assigned to the potential energy, but the difference - this difference would be the same, even if you change your reference level.
What is the reference point of gravitational potential energy?
Any point can be used as reference point, since the absolute amount of potential energy doesn't have any meaning; only the relative amount (i.e., increase or decrease between two positions) has. Quite often, one of the following standards is used: 1. For calculations near Earth's surface, the reference point is the floor. However, you can use any other reference point if it makes your calculations easier. 2. For astronomical calculations, the reference point is at an infinite distance. Thus, all potential energies have negative values.
What is the purpose of a reference point?
A reference point helps to explain why we are, where we are.

Does absolute potential energy both zero and negative at point of infinity?
There is really no such a thing as "absolute potential energy"; potential energy refers to the difference in energy between two points. For purposes of calculation, a convenient reference point is often chosen, and one such reference point is a point at an infinite distance.
What is the potential energy of a 40 N object 10 meters above its reference point?
the energy forms back into its original state,form, and size. The reference point would be 4.556
The moment a ski jumper lands has all of his potential energy been changed to kinetic energy?
Yes, as long as the reference point was the ground. Potential energy is completely based on the reference point, as U = mgh, h being the height.

What is the scientific definition of initial position?
point of reference-an indicator that orients you generally. it is used as a reference for comparing the heating and the electrical energy involved.
Does everyhting have energy?
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.

What is the fix reference point in photos?
What is the fixed reference point in the photos?
Where an object is with regard to a reference point is what?
Its position, relative to the point of reference.
