This animation shows that when two objects are dropped their vertical acceration will always be G will be constant in the location. This animation helps demostrate that no matter how much force is applied in the x direction, the object will fall at the same rate. It could be used for projectile motion. On the right adjust the x velocity for the blue ball and hit play.

This animation shows how refraction changes with different angles and indexes. This is useful because it can help us find how the index of refraction effects the angle of refraction. In the top left corner set the angle of incidence and in the bottom left corner set the index of refraction and the angle of refraction should bend more towards the normal as the index increases.
