Why is potential energy U?
U is the letter most similar to V – there are lots of times when, if V is used as a variable for a concept, then U is a variable for a similar concept. So potential energy became U, because someone might have been trying to make a connection with potential voltage.
Does U represent potential energy?
– In classical mechanics, U is often used to represent potential energy . Specifically, it’s used as a symbol for gravitational potential energy and elastic potential energy. – In electrodynamics, U is used to represent electric potential energy. – In thermodynamics, U is often used as the symbol for internal energy .
What is energy at rest called?
Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion.
What is the symbol of potential?

What word has the same meaning as electric potential?
electric potential, potential, potential difference, potential drop, voltage(noun) the difference in electrical charge between two points in a circuit expressed in volts. Synonyms: potency, potentiality, potential difference, potential, electromotive force, voltage, potential drop, emf.
What word would you use to describe voltage?
Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
What is Zener diode symbol?
Symbol of zener diode In zener diode, electric current flows from both anode to cathode and cathode to anode. The symbol of zener diode is similar to the normal p-n junction diode, but with bend edges on the vertical bar.
