Movement Path for Animation

"Hi, this is Cable on behalf of Expert Village. In a bouncing ball animation one of the first thing to do is make a plan for the bouncing ball is involve or make a motion after the ball. Especially a map for the one that the balls moves, how it hits, how many times does it bounces, draw your art another animation principle. So if you want to draw the line that would follow and you start on them outside of your animation drawn. We would have it bounce 3 times and then it goes off the page."
