Period (T)
the time it takes for an object to make one complete revolution
“n”
the # of revolutions
“t”
time
Equation for Period
T = t/n
Frequency
the amount of times an object has cycled within a given time period
equation for Frequency
F= n/t
Calculation for Frequency with period
F = 1/ T
Calculation for Period with Frequency
T = 1/F
What is Frequency measured in
Hz
Tangential Velocity (Vt)
The motion of an object with a constant speed, not constant velocity b/c direction is always changing
Equation for Vt
Vt = 2πr / T(period)
Equation for Period (T) with tangential Velocity
T = 2πr / Vt
