Velocity Converter

Velocity is a vector Quantity which is used to express displacement of any particle which has moved with respect to time, velocity mainly shows out, the Quantity of difference between the initial position and final position in an interval of time and with what speed the particle is changing its position is velocity. Velocity is consist of two things the speed and the direction in which the particle is propagating.

Now in order to get a clear idea of what is velocity, lets us suppose any particle which is at position A and has been moved to position B, here one thing to note is that the velocity will come into consideration when we will try to understand or we are interested in knowing with what speed that particle is propagating,

Velocity Converter

Another and one of the effective way to understand velocity is that velocity is when we include the speed with time,

Form position A to position B, with the speed the particle is propagating in a particular direction, with respect to time, this is known as velocity.

Velocity can be described as a point, this is known as instantaneous velocity hence velocity at a particular point is known as the instantaneous velocity.

RELATIVE QUANTITY

One of the important thing about velocity is that velocity is a relative Quantity, now in order to understand this we have to take an example. Suppose we have a bus which is moving now bus will have some sort of velocity when anyone who is standing on the ground will be related to velocity and the velocity of this bus will be 0, when it is taken with consideration with anyone sitting inside the bus.

Again one of the most important thing about velocity is that velocity is included with direction when where there will be any sort of change in direction it will encounter the change in velocity also.

How to calculate?

Velocity is the rate of change of position of any particle with respect to time, this means that in order to find velocity we require two aspects, that the change in position and the change in time, hence V= (p1-p2)/(t1-t2) where p1 and p2 are initial and final position and t1 and r2 s initial time and final time,

Hence with this have v=D/T, where D is displacement and t is that time taken for that displacement

SI units

The SI unit of velocity is M/s which is derived from the SI unit of displacement which is M and time which is T, you can also use KM/hr. or CM/sec for describing velocity.

Important notes

• Velocity changes with a change in time.
• In a circular motion, velocity changes at every point, since there is a change in direction at every point.
• when we consider Biochemistry, velocity is the number of reactions/sec which is catalyzed per mole of an enzymes
• velocity is always considered in terms of frame of reference, that means it is a relative Quantity
