Toss a construction made with simulated masses and flexible rods to see what happens. Find the effect of gravity by toggling it on and off. See if the rods are in tension or compression. Store and release energy. Have fun and learn.
Real Time 3D Physics enables the visitor play with an on-screen construction of masses and elastic rods and see a lot of physics at work at the same time. Pressing the "p" key lets the cursor pick up the construction, toss it around, let it swing like a pendulum, and watch what happens as it hits the ground. To investigate something less complex, there is also a system of two masses connected by a rod.
One of the most interesting features is the color code that shows if the rods are in compression or tension. As the construction swings, or as it hits the ground, the colors change with the forces on the masses.
Gravity can be toggled on and off, and it's fun to do this with the two constructions on the ground and see what happens.
