The green, blue, and red dots move at uniform angular acceleration. The vectors represent tangential and radial accelerations of the corresponding points. Run the applet to see how the vectors change with time.
(The scale factor for the tangential acceleration vectors is 5 times that for the radial acceleration vectors.) |

The red arrow has a non-zero initial angular velocity. After t = 0, the arrow undergoes uniform angular deceleration. Determine the following for the arrow:
average angular speed from t = 0 to the time when v = 0
angular speed at t = 0
angular acceleration
tangential acceleration
radial acceleration when angular displacement (theta) is 180 deg |

The black dot undergoes constant angular acceleration. The vectors represent the following:
blue: tangential acceleration of the dot
red: radial (centripetal) acceleration of the dot
green: vector sum of tangential and radial accelerations |
