The Applet CollectionThese applets enable you to study simple physical systems in a playful way. They are idealizations of realistic scenarios, which follow the proper equations that also govern the real experimental systems.Here is also a handy calculator (will open in a separate window): |
Kinematics |

Significant
Figures Try some exercises with significant figures on your own. |
GraphLab Playing around with the parameters (x0, v0, and a) of the simple kinematic equations for motion in 1D with constant acceleration. |
Vector Addition Practice with the concepts of graphical vector addition and subtraction. |
Projectile Simulation Shoot a cannon after selecting the initial speed and angle of the projectile. |
