The ease in/ease out at frames 0 and 30
are set with a positive tension value. The negative tension value helps to force the
motion for the teacup at frame 10.
But notice that frame 10 still slopes
down into the saucer.While the
motion of the fall and bounce are
better, the motion still needs a bit of
adjustment. The reason is that settings
for each keyframe in a motion
curve affect all the other keyframes.
You set keyframes before and after
frame 10, and the motion settings
before and after the frame affect
frame 10??™s settings. Fortunately, this
is easy to adjust.
8. Go to frame 10, and select the teacup.
Simply move it up on the Y-axis
enough so that it rests on the saucer,
as in Figure 6.18.

fixes the motion curve.
Chapter 6 Principles in Motion 237
You can add frames to a resting position by simply creating another keyframe. For example,
if you wanted the teacup to stay in place only until frame 150, you would create an
additional keyframe in the same position. Just think about your timeline process and what
you??™re trying to accomplish.
