Velocity |v| = f(r,T)

The Velocity calculator computes the magnitude of the instantaneous velocity in uniform Circular Motion circular motion as a function of the radius (r) and period of rotation (T).

INSTRUCTIONS: Choose your preferred units and enter the following:

• (r)  This is the radius of the circular orbit.
• (T) This is the period of the circular orbit.

Velocity: The calculator returns the magnitude of velocity in meters per second.  However, this can be automatically converted into other velocity units via the pull-down menu.

|V| = 2•?•r/T
