# What does the symbol W mean in physics?

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

## What is m and L in physics?

The mass of each little piece is: dm = λ dx, where λ is the mass per unit length of the rod. λ = M/L, where M is the rod’s total mass.

## What is L in moment of inertia?

Moment of inertia of a rod whose axis goes through the centre of the rod, having mass (M) and length (L) is generally expressed as; I = (1/12) ML2. The moment of inertia can also be expressed using another formula when the axis of the rod goes through the end of the rod.

## What does i and j mean in physics?

• ‘i’ is the horizontal component. • ‘j’ is the vertical component.

## What does λ mean in physics?

Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f. wavelength.

## What is this symbol γ?

Gamma /ˈɡæmə/ (uppercase Γ, lowercase γ; Greek: γάμμα gámma) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. In Ancient Greek, the letter gamma represented a voiced velar stop IPA: [ɡ].

## What is Little E in physics?

electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb.

## Is omega the last letter?

Omega (uppercase Ω, lowercase ω) is the 24th and last letter of the Greek alphabet. In the Greek numeric system, it has a value of 800. Pronounced [ɔ:] or ‘aw’ as in ‘raw’.

## What does F mean in physics?

F = force m = mass a = acceleration Newton’s Second Law.

## What does H mean in physics?

Planck’s constant, (symbol h), fundamental physical constant characteristic of the mathematical formulations of quantum mechanics, which describes the behaviour of particles and waves on the atomic scale, including the particle aspect of light.

## What is the moment of inertia of a rod of length L?

The moment of inertia of a rod of length ‘l’ about an axis passing through its centre of mass and perpendicular to rod is ‘I’. The moment of inertia of hexagonal shape formed by six such rods, about an axis passing through its centre of mass and perpendicular to its plane will be. No worries!

## What is the moment of inertia of a rod of mass m and length L about an Axisperpendicular to it and passing through one end?

Where, m is mass of rod, a is distance of axis from centre and I is moment of inertia along centre axis. Thus, the moment of inertia of rod along the axis perpendicular to one of its ends is ML23.

## What does i stand for in vectors?

1 Answer. Wataru. Oct 23, 2014. In the x,y-plane, they stand for the standard unit vectors. ⎧⎨⎩→i=(1,0)→j=(0,1)

## Which way is i and j?

Unit Vectors The unit vector in the direction of the x-axis is i, the unit vector in the direction of the y-axis is j and the unit vector in the direction of the z-axis is k.

## Why do vectors use i and j?

i is the unit vector in the horizontal direction, in the positive horizontal direction. If you want to go the other way, you would multiply it by a negative. And j is the unit vector in the vertical direction.

## What does lambda mean LGBT?

The gay community often uses the Greek symbol Lambda because it means “change.”

## What does V stand for in waves?

v is the velocity of the wave.

## What is W in Greek alphabet?

Digamma or wau (uppercase: Ϝ, lowercase: ϝ, numeral: ϛ) is an archaic letter of the Greek alphabet. It originally stood for the sound /w/ but it has remained in use principally as a Greek numeral for 6.

## What is P in Greek alphabet?

A common example is the Greek letter Pi, which is a mathematical constant and is used as the ratio of a circle’s circumference to its radius. Pi is commonly shortened to “3.14” Greek letters are also used in astronomy, to identify stars within a constellation.

## What is η called?

Letter. η • (i) (lowercase, uppercase Η) Lower-case eta, the seventh letter of the modern Greek alphabet. Its name is ήτα and it represents a close front unrounded vowel: /i/. It is often transliterated as either e or i.

## What is r in physics force?

The size of a frictional force is given by F, start subscript, f, end subscript, is less than or equal to, mu, R,Ff≤μR where R is the magnitude of the normal reaction force between the two surfaces and μ is the coefficient of friction between the two surfaces.

## Is omicron a Greek God?

According to Greek mythology, Omicron was a Greek God who was unhappy when people lived in peace, working harmoniously together to maximize their collective well-being and happiness.

## Which is bigger Omega or infinity?

ABSOLUTE INFINITY !!! This is the smallest ordinal number after “omega”. Informally we can think of this as infinity plus one. One formulation of ordinals is to treat them as sets of all smaller ordinals.

## What is VE in physics?

Answer and Explanation: -ve and +ve mean negative and positive respectively. They are often used in science laboratory notebook shorthand and are convenient ways for scientists to quickly write about the charges of lab equipment and chemical species.
