An object is traveling around a circle with a radius of 2 meters. If in 20 seconds the object travels 5 meters, what is its angular speed? What is its linear speed?
Also: What is the basic difference between angular and linear speed?
The linear speed:
Where:
- Linear speed
- Distance travelled
- Time (in which the distance is travelled)
__________________
Angular speed:
Where:
- = Linear speed
- = Radius
- = Angular speed (In radian)

The Difference:
Linear velocity is a change of speed in a straight line. Angular speed is the rate of change of angle with respect to time. These two are convertible in a case of a circle motion. In a circle, across a tangent, linear speed can be measured and across the arc traveled, angular speed can be measured.
