A wheel of the bike makes 20 revolutions for 12 seconds and has a diameter of 80 cm.
Determine:
a) its angular velocity
b) its tangential velocity
Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
