 Time period-

  • Time taken to complete one rotation

  • Formula-

                           T=\frac{2\pi }{\omega }

                            Where    

            If N= no.of revolutions and t=total time then

                           T=\frac{t }{N } or    (\omega =\frac{2\pi N}{t})

  • S.I unit seconds (s)

   

As \omega = 2\pi f.So\: \: \omega = 2\pi \times 5= 10\pi \: rad/sec
