Rotation speed (circulation)
Rotation (circulation) frequency is a physical quantity equal to the number of revolutions that a body makes per unit of time (1 second).
To find the rotation frequency, you need to divide the number of revolutions by the time it takes to make these revolutions:
Rotation frequency is the reciprocal of the rotation period:
The rotational speed shows how many revolutions are made in 1 second.
The SI unit of rotation frequency is the rotation frequency at which the body makes one revolution every second. This unit is designated as follows: [1/s] or [s -1 ] (read: second to the minus first power). The SI unit of frequency is called Hertz [Hz].
T—circulation period
ν — circulation frequency
N - number of revolutions
t is the time during which the body made N revolutions in a circle
As for the designations, please REMEMBER - THERE ARE NO hard and fast designation rules, in principle - designate them as you want, even with the letters “ш” and “ъ”
