Whats the difference between Gravity potential and electric potential?

Answer 1

Gravitational Potential Energy is dependent upon some mass (m) located at some height/distance (h) away from another mass which causes the first mass to experience a gravitational acceleration (g).
In other words, when two masses are separated by some distance both masses posses gravitational potential energy.

Electrical Potential is very similar to gravitational, but it deals with charges instead of mass.
When two (non neutral) electric charges are separated, the charges possess electric potential energy in that both charges feel an electric force acting upon them which causes acceleration. When these charges are held a given distance apart, they posses some potential energy.

Charged in and of themselves may also posses gravitational PE in that not only do they have an electric charge, but that also have mass (for example, electrons and Protons). In most cases, the gravitational PE is ignored since the electric force is so much greater than the gravitational force.

PE_g = mgh
in a uniform gravitational field.
PE_g = (G * M_1 * m_2) / r^2
Where G is the universal gravitational constant, m (and M) is the mass of the object, g is the gravitational acceleration, h is the distance the object is held above the gravitational field, and r is the radium between the two objects' centers of mass.
G = 6.67 E-11

PE_e = (k * Q_1 * q_2) / r^2
where k is Coulomb's constant (= 8.988 E9), Q and q are the charges on the two particles, and r is the distance between the centers of charge on the two particles.


EDIT:
Energy is of course measured in Joules.

Do not confuse "Electrical Potential" and "Electrical Potential Energy", although the terms are similar. Electrical Potential is just like any other energy, measured in Joules. Electrical Potential is measured in "Volts".
1 volt = 1 Joule / Coulomb
An electrical potential will cause an electric current, and electric current has a electrical power given the Electrical Potential * Current. Electrical current is given as the charge passing throug a given segment of wire per second, Coulomb / second.
Power = volts * amps

Answer 2

There are more similarities between the two potentials than there are differences.

The main difference between the two potentials is:

The gravitational potential DECREASES from zero (when the two masses are separated by infinite distance) to a minimum (negative) value, when the masses are close to each other.

The electrical potential of two same types of charges INCREASES from zero (when the two charges are separated by infinite distance) to infinity when the charges are close to each other. This is because gravitational force is attractive in nature whereas the electric force between two same sign of charges is repulsive in nature.

The electrical potential of two opposite signs of charges does not differ from that of gravitational potential.

Since the question is about differences, I am not narrating the similarities.

Answer 3

Gravity potential is the energy when the object is above the earth its maximum is when the object reaches its highest point in the air. Least when the object is on the ground.
Do not know Electric

Answer 4

gravitational potential energy is when an object could be pulled by gravity, but something is holding/stopping/slowing it such as air friction or the desk holding up ur computer . electrical potential energy is when voltage is pushing electrons through a conductor. in short gravitational energy is when gravity pulls something down, and electrical energy moves electrons.
