This site has a variety of review materials, mini quizzes, and other tools which cover both the prerequisite science material as well as much of the content material covered in introductory physics courses.

This graphically shows integrals or derivatives of any function you draw. You can create a function and then have the simulation show the integral and/or derivative of your function

This fantastic online graphing calculator is predominantly used for 2D display of functions, but it also has a very useful 3D version which can easily show vectors.

Vector Product
This simulation shows how projectiles move in 2D. The initial velocity and launch angle can be varied, which affects the projectile’s trajectory.
The resultant x, y, vx, and vy graphs can be shown.
