Animate a simple object like a bouncing ball - as it hits the ground, you can squash the ball flat and widen it. Although exaggerated, this animation is grounded in reality, because it creates the illusion of the ball being distorted by an outside force - just like in real life. You can apply squash and stretch to more realistic animation, too. But keep in mind the object’s volume. If the length of the ball is vertically stretched, its width must contract horizontally.
