electric potential energy:PE = k q Q /r. Energy is a scalar,not a vector. To find the total electric potential energy associated with a set of charges,simply add up the energy (which may be positive or negative) associated with each pair of charges. An object near the surface of the Earth experiences a nearly uniform gravitational field …

How do you calculate electric potential energy?
Electric Potential Formula: A charge placed in an electric field possesses potential energy and is measured by the work done in moving the charge from infinity to that point against the electric field. If two charges q 1 and q 2 are separated by a distance d, the e lectric potential energy of the system is; U = [1/ (4蟺蔚 o)] [q 1 q 2 /d]
What is the difference between electric potential and electric potential energy?
Yes, electric potential is the energy per charge of interest. Whereas, the electric potential energy is the energy at that point in space that is not per charge (because you don’t have a charge there yet). (1 vote)
What is the unit of potential energy?
This potential energy per unit charge is called electric potential (or simply potential). Like all work and energy, the unit of potential energy is the Joule (J), where 1 J = 1 kg鈭檓 2 /s 2 . The unit of charge is the Coulomb (C), and the unit of electric potential is the Volt (V), which is equal to a Joule per Coulomb (J/C).
