The formula to calculate Radial Velocity is:
\[ Vr = \frac{\Delta r}{\Delta t} \]
Where:
A radial velocity, also commonly referred to as angular velocity, is a measure of the change in radial position per unit of time.
Let's consider an example:
Using the formula to calculate Radial Velocity:
\[ Vr = \frac{3}{2} = 1.5 \, \text{rad/s} \]
This demonstrates that with a change in radial position of 3 radians and a change in time of 2 seconds, the radial velocity would be 1.5 rad/s.
