A fully functioning virtual version of a classic physics lab apparatus: Circular Motion. This app can be used to study circular motion, angular forces, friction, 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, with a few added benefits. An old school record player acts as the circular motion track. Various masses (discs and cylinders) can be added anywhere on the record in varying distances. Adjust the speed (rpm) to anything you want and then see what happens. Does the friction keep the disc on or does it go flying off? Add a wireless force sensor to measure the centripetal force. Weigh the different masses on the digital scale.
Unlike a regular lab, this virtual one has extra bonuses, too. See the instantaneous speeds in real time, both the tangential velocity and the angular frequency. Turn on the vectors to see the force and velocity vectors on the mass as it rotates around the record player. Use the mass multiplier to change the density of the mass while it's in motion. Try the lab today!
