Pick up a mass and place it on the end of a spring and watch the mass bob up and down. Pull it off the spring and try placing a different mass on the end of the spring. Or use both springs and place different masses on each one of them. Ready to measure? Just click the Start button and the height of the mass, the velocity at which it is moving, and the time will all be measured and plotted on a graph. Values go by too fast? No problem with this Interactive - just drag a slider backwards across the graph and view height, velocity and time values at any point on the graph.
As if that were not enough, you can also change the nature of the spring - changing both its stiffness and the amount of damping.
This simulation is so realistic it is almost as if you are manipulating the real thing. Grab a particle on a string and start wiggling it back and forth. Watch as the disturbance you create travels from particle to particle.
