This interactive program will let you draw two polygons which are then cut into pieces in such a way to be able to get rearranged to form the other one.
Coming soon.
This tool shows you the connection between rectangular triangles and the geomertic functions sine, cosine and tangens.
Coming soon.
Interactive tool to visualize the change in velocity when two masses collide.
Here you can see how light changes it's direction when entering another medium. For now only the refraction for air-to-water is available.
This simulation shows the influence of mass, length and starting angle on the pendulum's speed. The current speed is shown in a plot.
This simulation will show you how big a mass has to be to balance out a second mass. Both masses are connected via a rope running over a pulley. The first lies on a slope while the second one hangs down othe other edge.
Coming soon.
