This Demonstration considers a particle undergoing uniform circular motion. Assume a rotation period of 1 second and a radius of 1 meter. Use the "time" slider to move the particle around its circular orbit and the "radius" slider to set the radius of the orbit.


The first three boxes give the particle's position , velocity and acceleration .

Check the box "local frame" for the components of the particle's velocity and acceleration.

In the table, , and represent the magnitudes of the vectors , and , respectively; is the circumference of the orbit; is the orbital period; and is the angular frequency in rad/s. The expression equals the magnitude of , the centripetal acceleration.
