How do you calculate a rotating object's period of motion?

I am doing a lab and I have an object rotating in a uniform circle of radius 1.5 m at a rate of 25 revolutions in 20s.



I'm not even sure what period of motion means.How do you calculate a rotating object's period of motion?T=(2蟺)/w



where...

T is the period

w is angular velocity



Angular velocity is:

w=(revolutions*2蟺)/(change in time).



This simplifies to:

T=(change in time)/(revolutions)How do you calculate a rotating object's period of motion?Period of motion is the time it takes to complete one cycle.



It if completes 25 cycles (revolutions) in 20 seconds, then one cycle takes 20/25 = 0.8 seconds
