In classical mechanics, U is often used to represent **potential energy**. In particular, it is used as a symbol of gravitational potential energy and elastic potential energy. In electrodynamics, U is used to represent electrical potential energy.

## What does U mean in physics velocity?

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

## What does u stand for in physics in motion?

They are often referred to as the SUVAT equations, where “SUVAT” is an acronym from the variables: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.

## What does μ stand for in physics?

The lowercase Greek letter mu (µ) is used to represent the prefix multiplier 0.000001 (10 ^{–}^{6} or one millionth). For example, 0.000000001 farad or 10 ^{–}^{9} F of capacitance is commonly written as 0.001 µF.

## What is V and U in physics light?

Where v is the image distance and u is the object distance.

## What is the R in physics?

r = radius. R = resistance. R = molar gas constant.

## What is U in physics class 9?

u is initial velocity. v is the final velocity. a is acceleration. t is the time period.

## What does μ stand for?

Micro (Greek letter μ (U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 10^{−}^{6} (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”.
