Velocity and travel velocity

Uniform velocity
An object is said to have a uniform velocity if it moves equal distances ( s ) in equal interval of time. The velocity remains constant.

Velocity = 50km/ hr

Travel Velocity (V) = Distance travelled (s) / time taken (t) V = s/t
Rotary Velocity (V) = Circumference (n) multiplied by revolution per unit time ( Pi D ) V=Pi D n

Diameter = 0.6m, rpm = 100,
V= 3.142 x 0.6 x 100 = 188.5 m/min

Uniform accelerated velocity
Velocity (v) gradually increases at a constant rate (a). The acceleration is the gradual rate of increase or decrease of the velocity per unit of time.

The velocity after time = V=at
