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
eg. 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
