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.
This glossary of physics is a list of definitions of terms and concepts relevant to physics, its sub-disciplines, and related fields, including mechanics, materials science, nuclear physics, particle physics, and thermodynamics.
u in Physics: 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. The final velocity is denoted by v. a stands for acceleration. The time period is denoted by the letter t.
