If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
What describes electric charge?
An electric charge is one of several properties which particles such as electrons and protons have. This particular property comes in two varieties - called "positive" and "negative". Particles which have the same charge - two positive particles, or two negative particles - repel one another; particles with different properties (one positive and one negative) attract one another.
Is it possible for the electric potential at the center of the cube to be zero?
Electric potential is a scalar which means you merely add up all the potentials at the center of the cube while ignoring the direction it is pointed in. I supposed voltage (or electric potential) could be 0 if you have an even number of positive and negative charges all with the same distance from the center (if the charges are on the corners of the square the distances would in fact be the same).
Is an electric field a potential field?
no electric field is not a potential field .ELECTRIC FIELD IS A SCALAR QUANTITY WHERE AS POTENTIAL IS THE VECTOR QUANTITY. NO SCALAR QUANTITY HAS A FIELD SO THERE IS NO RELATION BETWEEN ELECTRIC FIELD AND POTENTIAL OR IN OTHER WORD POTENTIAL HAS NO FIELD <<>> An electric field is a vector field, because it has magnitude and direction. A pair of charged parallel plates has an electric field between them directed from the negative to the positive plate. The electric field is the gradient of the potential, which is another field but a scalar one. A field is just a quantity with a value that depends on positon. The potential is measured in volts and if one plate is grounded and the other at positive potential V, the potential rises from zero to V as the position changes from the lower plate to the top one.
What has potential energy?
Potential energy is a energy stored within a system as a result of the position or configuration of the different parts of that system.The types of potential energy are gravitational potential energy, which is energy due to height, and elastic potential energy, which is energy involved with a stretched or compressed spring.
If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
Why electric field is negative gradient of electric potential?
This is because potential decreases if we move further from a positive plate
What describes electric charge?
An electric charge is one of several properties which particles such as electrons and protons have. This particular property comes in two varieties - called "positive" and "negative". Particles which have the same charge - two positive particles, or two negative particles - repel one another; particles with different properties (one positive and one negative) attract one another.

Why do electric cell have two terminals?
They are the negative and positive terminals. Higher potential andl ower potential terminals
Why do atom have no electric charge even though most of their particles have charges?
Non ionic atoms have no electric charge, even though most of their particles have charge, because the positive particles (protons) balance the negative particles (electrons).

How do the particles of an atom differ in electric charge?
some is positive and some are negative and some are neutral and thats how there differ
What does electrical potential mean?
Electric potential is like electric potential energy, except electric potential energy requires that you have at least two charged particles: one charged particle (can be considered to be stationary) to produce the electric field and another charged particle to be affected by that electric field. If both charged particles are positively charged, then when you move the nonstationary charged particle closer to the stationary charged particle, potential energy of the system increases, because the charged particles naturally want to repel. However, let's say you remove that nonstationary charged particle and are left with just the single charged particle. There is no more potential energy in the system, because there is no other charged particle to be acted upon by the electric field. However, the single charged particle still emits an electric field. This field is what creates "electric potential." Even though there is no second particle in the system, if you were to place a second particle into the system (let's call it a test particle), its potential energy would be equal to the electric potential multiplied by the charge of the test particle. U = kq1q2/r (electric potential energy with 2 charges, where the 0 of potential energy is infinitely far away) V = kq1/r (electric potential requiring only 1 charge) V = U/q2 (electric potential is potential energy without the second charge) U = Vq2 (electric potential energy is electric potential multiplied by second charge) There is also a concept called gravitational potential, where it's gravitational potential energy divided by the test mass. It can be a negatively charged particle. In that case, electric potential decreases as you get closer to the negatively charged particle. Even though electric potential decreases, if you have two negatively charged particles, electric potential energy increases as you move the 2nd negative charge closer to the first charge. This is because multiplying 2 negative charges makes a positive: U = k(-q1)*(-q2)/r = kq1q2/r (assuming q1 and q2 are the charge magnitudes) So in this case, it's a little weird because that's how the math works. Nature has a tendency to reduce potential energy, but potential is different and doesn't work the same way. However if the test charge was positive, the sign of electric potential energy will be the same as electric potential with respect to location. V = k(-q1)/r = -kq1/r U = k(-q1)(q2)/r = -kq1q2/r Potential energy is not the same as potential! They are related, but don't get them confused. Energy is measured in Joules. Potential is measured in Volts. Completely different units. Volts = Number of Joules / Number of Coulombs. Electric Potential = Electric Potential Energy / Charge of Test Particle

Why do atoms have no electric charge even though most Of their particle have charges?
The negative particles (electrons) are balanced by the positive particles (protons).
What is the definition for positive charge?
having a deficiency of electrons ;having a higher electric potential
