SI units:
time:second
length: meter
speed:meter/second
velocity:meter/second.
Acceleration . . . (any length) divided by (any unit of time)2 , plus a direction Any velocity . . . (any length) divided by (any unit of time), plus a direction Time . . . second, minute, hour, day, week, fortnight, month, year, etc.
(any unit of length) / (any unit of time) is a unit that can be used for the magnitude (size) of velocity, and must always be accompanied by a description of direction. Without it, all you have is a speed, not a velocity.
No, velocity is not a derived unit. It is a fundamental physical quantity that measures the rate of change of an object's position with respect to time. Velocity is derived from the fundamental units of length and time.
Distance: Meters (or metres) Speed & velocity (meters per second). velocity also needs a direction but that isn't defined by SI units.
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.
A unit of speed is (any unit of length) divided by (any unit of time). A unit of velocity is any unit of speed, along with a direction.
Acceleration . . . (any length) divided by (any unit of time)2 , plus a direction Any velocity . . . (any length) divided by (any unit of time), plus a direction Time . . . second, minute, hour, day, week, fortnight, month, year, etc.
Speed is the rate of change of position per unit time. The dimension is Length / Time. Common units are meters per second, miles per hour, feet per second. Velocity is nearly the same (same dimensions), except that velocity is a vector, meaning that it has direction as well.Now acceleration is the rate of change of velocity. It also is a vector. Its dimensions are Length/(time^2). Typical units are meters/sec^2 and feet/sec^2.

Speed measured in units is called velocity. Velocity is a vector quantity that expresses the rate of change of position with respect to time, and includes both the speed and direction of an object's motion.
velocity is the distance divided by the time it takes to go that distance. let velocity equal V let distance equal D let time equal T v = d/t velocity has units of length per rate distance has units of length time has units of rate the length can have units such as 1) meters, centimeters, millimeters, kilometers 2) feet, inches 3) yards the time can have units such as 1) seconds, minutes, hours, years it depends on which system you are using for you units then you will know which units to choose from. the most common is meters per second (m/s)
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.
A mile is a unit of length. An hour is a unit of time. The two units are therefore incompatible without some unit of velocity or speed.
Velocity = length travelled per unit of time = (L)/(T) In other words, in the equation of motion of a particle traveling at a uniform velocity(V) for a time (T), the distance travelled would be L = VT.
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).
