The simulation of a pendulum below shows the relationship between angular position, angular velocity, and angular acceleration. Graphs of angular position, angular velocity, and angular acceleration as a function of time are shown.

Is the angular acceleration of the pendulum constant?

As the pendulum travels from A to B, is the angular velocity positive or negative? Is the angular acceleration positive or negative?

As the pendulum travels from B to C is the angular velocity positive or negative? Is the angular acceleration positive or negative?

As the pendulum travels from C to B is the angular velocity positive or negative? Is the angular acceleration positive or negative?

As the pendulum travels from B to A is the angular velocity positive or negative? Is the angular acceleration positive or negative?

At what point(s) is the angular speed a maximum? At what point(s) is the magnitude of the angular acceleration a maximum?

At what point(s) is the magnitude of the tangential acceleration a maximum? At what point(s) is the magnitude of the radial acceleration a maximum?

What does the blue vector represent? What does the green vector represent?
