# In what unit is velocity measured?

Velocity is the ratio of two fundamental physical quantities: distance and time, and is

computed as the distance an object moves divided by the time in which it moves. In

SI units distance is measured in meters, and time in seconds. Therefore in SI units

velocity is measured in meters/sec. However velocity can be measured in any units

of distance per time: miles/hour, inches/year, micrometers/decade. As long as you

have a unit of distance in the numerator and a unit of time in the denominator you

have an acceptable unit for velocity.

So far, to this point, what you have is the * size*
of the velocity, also called "speed".

To make a **velocity** out of a **speed**, you must
indicate the * direction* of the speed.

### What is the meaning of speed velocity and acceleration?

Speed: Distance moved per time unit (rate of change of
position).
Velocity: Similar to speed, but velocity is a vector. In other
words, the word "velocity" is used in physics, when the direction
of movement is relevant.
Acceleration: Change of velocity per unit time (rate of change
of velocity).
Both speed and velocity are measured in meters per second (or
any other unit of length divided by a unit of time), while
acceleration is measured in meters per second squared (or any other
combination of units of distance / time / time).

discharge velocity is the quantity of flow that flows through a

seepage velocity
the actual rate of movement of the water as measured with dye
tracer for instance, is the seepage velocity

###### Asked in Science, Physics

### What is change in velocity of a moving body in unit time called?

Acceleration.
This is measured in metres per second per second.
As you pointed out in the question this is change in velocity
(or speed) over a specific time period.
The equation for acceleration is:
Acceleration (m/s/s) = delta v (change in velocity measured in
m/s) / delta t (change in time measured in seconds)
