Symbols for physical quantities and their international units

symbol | quantity | SI unit |
---|---|---|

ΦE | electric flux | newton meter squared per coulomb, volt meter |

U, UE | potential energy, electric potential energy | joule |

V, VE | voltage, potential, electric potential | volt |

ℰ | electromotive force, emf | volt |

**What is the weird U symbol 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.

**Why are Greek letters used in physics?**

Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.

**What is W called in physics?**

watt (W) probability. unitless. momentum. kilogram meter per second (kg⋅m/s)

**What does P stand for in physics electricity?**

Electric power (P) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅V= 1 W.

#### What is μ in math?

μ = ( Σ Xi ) / N. The symbol ‘μ’ represents the population mean. The symbol ‘Σ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.

**What is Ø in physics?**

Ø is used for the empty set and I think they should have use ∆Q not ØQ. ∆ is used to denote a finite amount of something:∆t-some amount of time, ∆x some distance in the x direction,∆Q some charge.

**What is Ø in math?**

The letter “Ø” is sometimes used in mathematics as a replacement for the symbol “∅” (Unicode character U+2205), referring to the empty set as established by Bourbaki, and sometimes in linguistics as a replacement for same symbol used to represent a zero. Slashed zero is an alternate glyph for the zero character.

### What did we use Makaton for in lockdown?

We used Makaton signs and symbols and they picked up English quickly. As the rest of the class knew a little Makaton too, they were able to make friends and communicate. During lockdown, my Makaton journey has gone further, and I have used it with encouraging language development and sentence construction through face to face and online learning.
