bouncing ball

I had to animate a ball bouncing in photoshop, here is the result of it bouncing using the principles of stretch and squash  and momentum which i think i achieved with this animated gif underneath

I learned that it is easier and quicker to make a ball bounce on photoshop then on traditional paper (flipbook animation) because first i have tools such as onion skin which allow me to see the frames underneath and above of the current frame, also i have the ability to move the ball to where i please because of the transform tool which is really handy.

I prefer animating digitally because it is easier to rub out mistakes and quicker to finish animations within 10 minutes rather then more than an 30 minutes which takes a while to do on paper,
