## What does X and T mean physics?

Like average velocity, instantaneous velocity is a vector with dimension of length per time. The instantaneous velocity at a specific time point t0 is the rate of change of the position function, which is the slope of the position function x(t) at t0.

## What is this called X?

more The letter “x” is often used in algebra to mean a value that is not yet known. It is called a ” variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol.

## What does Y represent in physics?

Cartesian y -axis basis unit vector. unitless. kinetic energy. joule (J) Boltzmann constant.

## What does T stand for in physics?

T. = constant. P = pressure V = volume T = temperature The “Ideal Gas Law”. For “ideal” gases (and also for real-life gases at low pressure), the pressure of the gas times the volume of the gas divided by the temperature of the gas is a constant. Modern Physics and Relativity.

## What is current formula?

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

## What does the symbol ∆ mean?

∆: Means “change” or “difference”, as in the equation of a line’s slope: 2. 1. 2.

## What does XX mean?

XX means ” two kisses.” ( As a general rule, an uppercase X represents a big kiss, and a lowercase x is a light kiss (a peck).

## What are () called in English?

They are called quotation marks. And in the U.S, the () are called parenthesis, and the [] are called brackets. Even in math.

## What does 4 mean in math?

In mathematics, the number 4 represents a quantity or value of 4. The whole number between 3 and 5 is 4. The number name of 4 is four.

## 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 D in physics stand for?

“d” means change in the limit that the change is infinitestimal. in your particular exapmle: really means “average” current because that’s total change in charge over total change in time: in fact it means., now when in the limit of very small change. ie.

## 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 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 the meaning of U in physics?

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

## What does G mean in physics?

The universal gravitational constant (G) relates the magnitude of the gravitational attractive force between two bodies to their masses and the distance between them. Its value is extremely difficult to measure experimentally.
