Apple Motion 4 - Manual (Page 533)

This rotates the minute hand clockwise at a continuous rate.
5 Select the hour hand layer, Control-click its Rotation parameter in the Properties tab, then
choose Rate from the shortcut menu.
6 In the Behaviors tab, set the Rate parameter to –4.
When you play the project at this point, you can see that the hour hand and minute hand
rotate clockwise at rates replicating the relative movement of real clock hands.
Tip: To make the hands of the clock appear to “tick,” you can apply the Quantize Parameter
behavior to the Rotation parameter of the hands and adjust the Step Size to accommodate
your animation.
Now it’s time to make the pendulum swing. You should have already adjusted its anchor
point to be at the top. This way, the bottom pendulum layer will swing properly.
7 Select the pendulum layer, Control-click the Rotation parameter in the Behaviors tab,
then choose Oscillate from the shortcut menu.
8 In the Behaviors tab, set the Oscillate behavior’s amplitude to 20.
