## What is the meaning of V in physics?

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 V stand for in physics speed?

The instantaneous speed of an object is then the magnitude of its instantaneous velocity. v = |v| Speed tells you how fast. Velocity tells you how fast and in what direction.

## Does V stand for velocity in physics?

If an object is moving in one direction then ” V” represents both velocity and speed and “D” represents both distance and

## What is V and U in physics mirror?

The distance between the object and the pole of the mirror is called the object distance(u). The distance between the image and the pole of the mirror is called Image distance(v).

## What does V not mean in physics?

The symbol v_{} [vee nought] is called the initial velocity or the velocity a time t = 0. The symbol v is the velocity some time t after the initial velocity. It is often called the final velocity but this does not make it an object’s “last velocity”.

## What does V 2f mean in physics?

Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s).

## What is V in the formula?

v = final velocity. a = acceleration. t = time. Use standard gravity, a = 9.80665 m/s^{2}, for equations involving the Earth’s gravitational force as the acceleration rate of an object.

## What is velocity in physics class 9?

Velocity: Velocity is the speed of an object moving in a definite direction. The SI unit of velocity is also metre per second. Velocity is a vector quantity; it has both magnitude and direction.

## Who discovered velocity?

The speed of a point at any instant may be approximated by finding the average speed for a short time interval including the instant in question. The differential calculus, which was invented by Isaac Newton for this specific purpose, provides means for determining exact values of the instantaneous velocity.

## What is V and U in light?

if v is the image distance and u is the object distance. So, It can be also defined as the ratio of the height of the image to the height of the object.

## In which mirror image is always erect?

Solution: Convex mirror always forms an erect and virtual image.

## What is a mirror formula?

A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’. The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors).
