# Question: What Is I In Physics?

I = moment of inertia.

## What do V and I stand for in physics?

In your case, it most certainly means velocity only. Not speed. There is a difference between the two, and it is very important for determining what physics equations look like. This is because velocity is a vector quantity. By that, I mean velocity is defined both by its magnitude (speed) and its direction.

## What does Triangle Y mean in physics?

What does position mean? In physics, we love to precisely describe the motion of an object. The variable x is often used to represent the horizontal position. The variable y is often used to represent the vertical position.

## What does V in physics mean?

v = velocity of the charge. B = external magnetic field. θ = angle between the direction of motion and the magnetic field The force on a charge q as it travels with velocity v through a magnetic field B is given by this formula.

## What does P stand for in physics?

p = pressure. p = momentum. π = 3.14. Pa = pascal (pressure)

## 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 full form of SI unit?

The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity)

## What does ∆ mean?

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

## 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.
