The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
8 mar 2024 · Constants in Physics are fundamental values that remain unchanged across different contexts and experiments. These constants are universal in nature and are independent of the unit system used. They are essential for verifying the accuracy of theories and enabling practical applications based on those theories.
25 maj 2023 · 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. What does u mean in physics velocity? Initial Velocity is the velocity at time interval t = 0 and it is represented by u.

This is a list of common physical constants and variables, and their notations. Note that bold text indicates that the quantity is a vector.
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).
