Symbols representing physical quantities, units, mathematical operations and relationships, astronomical bodies, constellations, and the Greek alphabet.
Both of voltage description "U" and "V" are proper, however it must be mentioned that in European notation "U" describes voltage source while "V" describes rather voltage potential. It means that U = V1 - V1 (voltage is a difference between voltage potentials).
This is a list of common physical constants and variables, and their notations. Note that bold text indicates that the quantity is a vector.
5 maj 2023 · In physics, the letter μ is commonly used to represent the coefficient of friction and magnetic permeability. The coefficient of friction refers to the ratio of the frictional force (F) resisting the motion of two surfaces that are in contact to the normal force (N) that’s pressing the two surfaces together.

The letter u is used in physics to denote the sign of potential energy, as well as the initial velocity and the object distance in ray optics. In the equation v = u + a t , The initial velocity is u .
