Horizontal Motion: Constant velocity
Vertical Motion: Constant downward acceleration

Student Comments:

"The interactive portion was fabulous! I liked the lines over the position of the ball over time when you click on it. It made a great visual. It will stick with me!"

"I think interactivity is a good idea when trying to teach any kind of analytical problem. Inquiry-based learning should be used more often!"
