Ball Study #1

Assignment: Ball#1


Use Adobe Animate to create an animation of two balls falling from the top of the screen to a ground line. One ball should be very bouncey, give the other ball whatever properties you like. Here’s a simple example with 3 different balls.

Use the following file format: 24fps, width: 1280px | height: 720px. Save your .fla file and export your animation to Quicktime (review exporting instructions in OpenLab Instructions). Upload your animation to Vimeo or Youtube.

Details for exporting to Quicktime are on Week Two page.

12 Principles Applied: Squash & Stretch and Slow in & Slow out

Let’s review two of the 12 principles of animation, Squash & Stretch and Slow In & Slow Out, and let’s apply them to an animation of a ball falling from the top of the screen. Here are some things to keep in mind as you draw your frames:

  • Create a ground layer. Also consider creating a vertical guide so that your ball falls at a straight angle.
  • The volume of your ball should be consistent across frames.
  • The speed of the ball should increase as it gets closer to the ground (to mimic the physical properties of gravity).
  • The amount of squash & stretch, the speed of the fall, the number and height of bounces once it hits the ground will all depend on the mass you want your ball to have – how heavy is your ball? what material is it made out of? All this will affect how you draw your frames.
  • Consider adding details such as shadows, fills, finger  holes etc.


Create a new post on your OpenLab portfolio. Your post should include a link to your Vimeo or Youtube video as well as a short description (reflections on your process, challenges, goals etc. are also welcome).

This assignment is due February 18. Submit the following files on the following platforms:

  • After posting the video on YouTube or Vimeo, create a post on your OpenLab portfolio
  • OpenLab discussion board: Reply to the “Ball Study #1” discussion post with a link to your OpenLab post
  • Blackboard: .fla file and a link to your OpenLab post.
