Designing animations part 3 – using curves

The linear movement exists only in theoretical physics. Why not make the movement a bit more realistic with the ease in and ease out curves? In this recipe, you will add a curve to the animation you built in parts 1 and 2 of Designing animations, so that the ball will start moving slowly, then increase its speed, and then slow down again before stopping. 

By the end of this recipe, you will understand how to add curves to your animations, making them more realistic and appealing.
