Components of the Velocity Vector in Projectile Motion QT Movie (464K)
A ball is tossed into the air with no air resistance. Shown are the velocity vector's components at the ball travels on a parabolic arc. Velocity Vector IP Simulation.

Student Target QT Movie (248K)
A slow moving projectile is launched directly at a student hanging motionless from a traipse bar. Having not done his homework on freefall, he reasons that he should let go at the moment the projectile is launched so that he can drop out of its way. The move demonstrates that the projectile and student fall downward with the same acceleration and the projectile will always intersect the student's path under these conditions.

Vector on the Great Salt Flats QT Movie (188K)
A test car traveling at 250 km/hr on the salt flats in Utah. The car starts out traveling at an angle of 18.0⁰ North of due East for 3.50 minutes. The car then turns 24.0⁰ to the North from its current heading and travels for 5.50 minutes. Shown is the resulting vectors of the distance the car moves in order to return to its starting point.
