A fully functioning virtual version of a classic physics lab apparatus: Simple Harmonic Motion. This app can be used to study Hooke's Law, explore the conservation of mechanical energy, use spring principles to find unknown weights, and more. Use it as a lab replacement in the classroom, as a demonstration tool, as a study aid for homework, or just for exploration.
This apparatus is just like the real thing. A large vertical spring is hanging from a stand, and various known and unknown masses can be put on the end. Start it at equilibrium, or start it at the top or bottom. Use the built-in stopwatch to take measurements.
Unlike the classroom version of the lab, in this app you'll be able to slow the motion down to get a better look at what's happening. Half speed, quarter speed, or even paused. You can also choose to dampen the spring with just a click of a button. And all while the spring is in motion, the position is being automatically graphed. There's even a real-time graph showing the kinetic and potential energy of the mass while it's moving up and down. Try the lab out today!
