What does C stand for in physics?
The speed of light is defined as the speed with which a light photon travels in the vacuum. It is denoted by the alphabet c and measured using SI unit m/s.
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.
What does R mean in physics?
universal gas constant, also called molar gas constant or gas constant, (symbol R), fundamental physical constant arising in the formulation of the ideal gas law.
What does F stand for in physics?
F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. W = mg. W = weight. m = mass.
What does ω mean in physics?
Angular frequency (ω), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second. Angular frequency (in radians) is larger than regular frequency (in Hz) by a factor of 2π: ω = 2πf.
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.
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 does ∼ mean?
“∼” is one of many symbols, listed in the Wikipedia article on approximation, used to indicate that one number is approximately equal to another. Note that “approximately equal” is reflexive and symmetric but not transitive. “∼” is one of many symbols used in logic to indicate negation.
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 does this symbol mean ≅?
≅ (approximately equal to)
What is a subscript in science?
Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of. atoms of that element. If an element does not have a subscript, then it is understood that the subscript is 1. Li2Cl3 has two lithium atoms and three chlorine atoms.
What does a subscript 2 mean?
2. The subscript denotes what term of the sequence you are considering; first, second, third,…, nth,… In the instant case, Fn is the nth Fibonacci number; F1 is the first Fibonacci number, 1; F2 is the second Fibonacci number, 1; F3 is the third Fibonnaci number, 2; etc.
What do subscripts represent?
The number of atoms of each kind is indicated by a subscript following the atom. If there is only one atom, no number is written. If there is more than one atom of a specific kind, the number is written as a subscript following the atom.
What does P mean physics?
Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p.
What is the W in physics?
The watt (abbreviated W) is the International System of Units’ (SI) standard unit of power (energy per unit time), the equivalent of one jouleper second.
What is K physics?
Boltzmann constant, (symbol k), a fundamental constant of physics occurring in nearly every statistical formulation of both classical and quantum physics.
Is F MA the same as E mc2?
Relationship of E = mc2 to F = ma and Gravity. A required modification of Newton’s second law of mechanics, F = ma force equation, to make it compatible with Einstein’s E = mc2 energy equation is presented in the simplest terms practical.
What does T stand for in physics?
In the field of physics, the letter ‘T’ is often used to denote the period of oscillation (commonly reffered to as simply ‘period’). The period of oscillation can be defined as the duration of time between one wave and the next one passing the same spot.
What are the 3 formulas in physics?
The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²
What is this called θ?
Theta (uppercase Θ, lowercase θ) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth. In the system of Greek numerals it has a value of 9.
How is Ω pronounced?
How do you say λ?
What does V stand for in waves?
v is the velocity of the wave.
What is V FΛ?
The wave equation: v = fλ Wavelength = = the length of one. wave (m) Frequency = f =
