What is the gravitational potential at infinity?
With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.

A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
How is gravitational potential energy different from potential energy?
It is different because gravitational potential energy is when something is getting pulled by gravity and potential energy is stored energy which means that it is not moving and the energy is not getting released as gravitational energy is.
Is Book on a high shelf chemical or potential energy?
Potential energy.
Define elastic potential energy and gravitional potential energy?
Gravitational potential energy, is the energy an object possesses by reason of its position in a gravitational field. While elastic potential energy, is the energy stored by a material or object as a result of deformation e.g. the energy stored in a bow when it is stretched.

What is the significance of negative energy of electron in an orbit?
Potential energy levels are often given as negative numbers. In the case of an electron, it's potential energy due to its location relative to the positively charged nucleus; the further away from the nucleus, the higher the energy level of the electron. So for convenience, physicists like to define potential energy levels at infinite distance (or separation) as "zero", and all others become negative. Since these forces (gravity, electromagnetic force) fall off with the square of distance, potential energies at finite (nonzero) distances aren't "negative infinity".
What does not have energy?
Any object that is at "level zero" has zero potential energy. In the case of gravitational potential energy, this level is sometimes defined to be ground level, sometimes (in Astronomy) at an infinite distance (in this case, any object that is closer than infinity has a negative potential energy).Any object that is at "level zero" has zero potential energy.

Can gravitational potential energy be negative?
In potential energy, the important thing is the increase or decrease in energy; any absolute energy level is arbitrary. So, it all depends on what level is arbitrarily defined as zero. For example, if you define the floor level as zero, then anything above that will be positive, anything below that will be negative.
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.
Why total electronic energy is negative?
In the case of potential energy, what matters is the difference in potential energy. Any "absolute potential energy" is an arbitrary definition. If you define a certain reference height as "zero height" and therefore "zero potential energy", anything above that would have a positive potential energy (as compared to the reference height), anything lower would have a negative potential energy. In Astronomy, for conveniencen, two objects at an infinite distance are often defined as having zero potential energy - thus, by definition, anything closer by would have a negative potential energy.In the case of potential energy, what matters is the difference in potential energy.

What is absolute potential energy?
Gravitational potential energy is defined as the work performed in moving the mass from infinity to the point concerned in the gravitational field. It will be given in negative. gravitational PE = - G M m / r^2 Here G - universal gravitational constant. M - mass which produced gravitaional field. m - the mass of the object. r - the distance of the point from the centre of the M, where the object has been borught.
When negative work is being done what happens to potential energy?
Negative work increases potential energy.
When is energy negative?
Because of the laws of enthalpy and entropy, free energy is always increasing. However, in endothermic reactions, or chemical reactions that require energy to occur, net free energy is negative because the energy is "lost" to the environment as it is bonded in the reaction. Energy is often defined in reference to something else, and the sign of the energy is a function which direction is flowing. If energy (heat) flows from a system to the environment, the enthalpy change is negative (exothermic), whereas if energy flows from the environment to the system, the enthalpy change is positive (endothermic).
What is the relationship between force, negative derivative, and potential energy in a system?
In a system, force is related to the negative derivative of potential energy. This means that the force acting on an object is equal to the negative rate of change of its potential energy.
Why the values of gravitational potential near to an isolated mass are all negative?
The gravitational potential near an isolated mass is negative because it is defined as the work per unit mass required to bring an object from infinity to that point. Since energy is required to move an object against the force of gravity, the potential energy is negative close to a mass as work is done to move an object towards the mass against its gravitational pull.
