Circular Motion 2

Question 1

What is a period?

Answer 1

the time it takes for one complete revolution, measured in s/cycle SEOCNS SEONCD

Question 2

What is frequency?

Answer 2

the number of revolutions in a given time
T=1/f OR f=1/T

from Hz (per sec) to rpm (per min)
#cycles/second x 60/1min

1 rpm = 60 Hz

Question 3

How many Hertz is in one rpm, and what are they measured in?

Answer 3

Hz PER SECOND
rpm PER MINUTE
60 HZ per one rpm

Question 4

Formula for speed, and what should you do?

Answer 4

Fc=2piR/T
makae sure youre working with Hz, then find T using T=1/f, then substitute
make sure you have the correct units; is speed in km/h or m/s? convert to m/s means dividing by 3.6
