Constant velocity: is the speed at which an object travels equal displacements in equal times. Variable velocity: It is the speed at which an object cuts different displacements at different times.
We need to derive the relation between the three types of velocities, that are RMS velocity, average velocity and most probable velocity.
In simple words, velocity is the speed at which something moves in a particular direction. For example as the speed of a car travelling north on a highway, or the speed a rocket travels after launching. The scalar means the absolute value magnitude of the velocity vector is always be the speed of the motion.
Velocity = Displacement/Time. or V = S/t,SI unit of velocity is metre per second. In Detail: The velocity of an object is the rate of change of its position with respect to a frames of reference and is a function of time.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time ( ...
So, what's the difference? Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity. Imagine something moving back and forth very fast: it has a high speed, but a low (or zero) velocity.
Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed.
Velocity can be changed in following different ways : (1) By changing only magnitude of velocity. (2) By changing direction of velocity. (3) By changing both magnitude and direction of velocity.
Uniform velocity: an object is said to be moving at the uniform velocity it covers equal displacements in equal intervals of time. Variable velocity(Non-Uniform velocity): an object is said to be moving at variable velocity if it is covering unequal displacements in equal distances of time.
The SI unit for velocity is meter per second (m/s). The basic formula to get velocity is distance(m)/time(s).
Velocity describes how position changes; acceleration describes how velocity changes.
Newton's first law states that an object will move at a constant velocity -- that is, in a straight line at a constant speed -- unless acted upon by an outside force.
Velocity is the speed in a particular direction, and it is typically measured in meters per second (m/s or ms−1). The difference between velocity and speed can be illustrated by a person walking around in a circle at a constant speed of 0.5 meters per second.
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
The correct answer is Light. The speed of light in the air is 3 × 108 m/s. The speed of light in a vacuum is 186,282 miles per second (299,792 kilometres per second). In theory, nothing can travel faster than light.
