It is perpendicular to the linear velocity v and has the magnitude ${a}_{\text{c}}=\frac{{v}^{2}}{r};{a}_{\text{c}}={\mathrm{r\omega }}^{2}\\$. Use this data to calculate Earth's radius. Period and frequency are reciprocals of each other. Powered by Create your own unique website with customizable templates. The formula for centripetal acceleration is given by: is the centripetal acceleration, is the velocity and is the radius of the circular path. 84 rad/s) a r = 5. A circular loop would cause a jolting change in acceleration at entry, a disadvantage discovered long ago in railroad curve design.
