## What is V and U in light?

if v is the image distance and u is the object distance.

…

It can be also defined as the ratio of the height of the image to the height of the object..

## What is the initial velocity?

Therefore, the initial velocity is the velocity of the object before the effect of acceleration, which causes the change. After accelerating the object for some amount of time, the velocity will be the final velocity.

## Is V positive in concave mirror?

➡ For convex mirrors, the image is always virtual. Let, u = object distance from pole of a mirror. … ➡ When the image is virtual, then “u” is as it is negative, “v” is positive, ”f” is negative. THUS, IN CASE OF CONCAVE MIRROR, FOCAL LENGTH ALWAYS REMAINS NEGATIVE.

## Can initial velocity be zero?

We generally consider initial velocity is equal to zero(u=0),only when the object starts from rest. Generally at time (t=0),the initial velocity is zero. When a body starts from rest or it changes it direction of motion,it is called as initial velocity.

## What does V mean in physics?

voltvolt (V) volume. cubic meter (m3) shear force. velocity.

## What is V and U in physics?

The equations of motion relate to the following five quantities: u – initial velocity. v – final velocity. a – acceleration.

## What does V mean in physics velocity?

instantaneous speedv → |v| 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.

## What does u stand for in physics?

Base Unit. (see note 9) Velocity. v, u, v. m/s.

## Is Vo initial velocity?

The initial linear rate of product formation is called the initial velocity, or vo. It is one of the most important characteristics of any enzyme-catalyzed reaction. One factor that affects the initial velocity is the substrate concentration, [S].

## What is difference between initial velocity and final velocity?

Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.

## What is V motion physics?

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”.

## Is V U at dimensionally correct?

The dimensional formula of u is [M0LT-1]. The dimensional formula of v is [M0LT-1]. … Here the dimensions of every term in the given physical relation are the same , hence the given phyical relation is dimensionally correct.

## What does U mean in velocity?

u is initial velocity in m/s. t is time ins. For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. … Velocity is defined as a vector measurement ofthe rate and direction of motion.

## What is V and U in mirror formula?

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). The distance between the Principal focus and pole of the mirror is called Focal Length(f).

## Is V negative in concave mirror?

And for image distance, V in lens it is taken as positive in Convex lens since image is formed on +X side. It is taken as negative in Concave lens since image is formed in -X side of the Cartesian. In Concave mirror V is taken as positive and negative for convex mirror.
