What is the Angular Displacement during a Time Interval?
A child on a merry-go-round takes 3.1 s to go around once.
What is his angular displacement during a 1.0 s time interval?
“The period (T) is the duration of one cycle in a repeating event”
Period: T=3.1 seconds
Time: t= 1.0 second
In order to find Angular displacement(Δθ), we need angular speed.
First step is to find Angular speed (ω).
2π/3.1= 2.02 rads/sec
2.02 × 1.0= 2.0 rad
Δθ= 2.0 rad
