# FAQ: What Does A Stand For In Physics?

A = nucleon number (atomic mass) a = acceleration.

## What is A and V in physics?

a = acceleration ∆v = change in velocity ∆t = elapsed time The definition of acceleration.

## 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 is current formula?

The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

## What does V 2f mean in physics?

Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s).

## What is the R in physics?

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

## What is the difference between M and M in physics?

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Mass is denoted using m or M. Weight is mass multiplied by the acceleration of gravity (g).

## What does P mean in physics?

Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. The useful thing about momentum is its relationship to force.

## What is this symbol μ?

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 106 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”. The symbol for the prefix is the Greek letter μ (mu).

## What is the symbol of force?

A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol F (formerly P).
