This blog post is about an animation exercise that helps to understand the basis of important principles such as timing, spacing, archs, squashing and weight.
We used a pre-made rig of a ball to focus one on the movement. The goal was to make the bouncing look as real as possible. At first, we had to make a sketch of a ball that helped us to understand the movement:

Then, we created a key points of the animation, as it was referenced in the sketch. The key points helped to understand the movement. The first version of the animation:
The second version after the feedback:
In conclusion, this exercise made me realise that the easiest movement as a simple bouncing ball can be actually very complicated. The second thought that this assignment led me to is to never underestimate the main principles of animation.
