This simulation allows you to play with kinematics: motion of a particle under gravity. You can change the value of gravity, and the friction due to air resistance (b*v²). You can also change the initial velocity vector by clicking on the tip and dragging it around. Remember that if you enable friction, then you have to also worry about mass!
