Change the frames per second speed
The frame rate, measured in frames per second (fps) is the speed at which
the animation plays. By default, Flash animations play at a rate of 12 fps,
which is ideal for web animation. Sometimes, however, it's desirable to
change the fps rate. You'll now change the frame rate to 36 frames per
second, which will make the tire appear to bounce more rapidly.
1. Click the Stage, away from any objects.
2.
In the Property inspector, type 36 in the Frame Rate text box.
The frame rate applies to the entire Flash document, not just to an
animation within the document.
Change the acceleration and deceleration
By default, tweened frames play at a constant speed. With easing, you can
create a more realistic rate of acceleration and deceleration. Positive values
begin the tween rapidly and decelerate the tween toward the end of the
animation. Negative values begin the tween slowly and accelerate the tween
toward the end of the animation. You'll now add both positive and negative
easing values to your animation.
