Today's animation session focused on the distinction between timing and spacing necessary to create realistic motion.
In order to develop an understanding I produced two separate experiments.
The first is simple linear motion of a ball. The uppermost ball moves at a constant rate, whereas the second accelerates and and decelerates. More tightly spaced frames produced an illusion of slowing, whereas spaced out frames created a sense of speed. Acceleration/deceleration was achieved by staggering the increase/decrease in the spacing of each frame.
The second experiment was with motion along a curve or about a pivot, using pendulums. The first - stuck to a horizon line, was to illustrate incorrect movement when a curve was expected, one shows curved motion at a constant speed, and one shows a more natural motion, accelerating and decelerating at it's trough and peaks.
