Angular acceleration of a Contracting System Model
The EJS Angular Acceleration of a Contracting System model shows a mass and pulley system to illustrate what happens when a rotating system contracts. When the centripetal force has contracted a rotating system to half its initial radius then: (1) The tangential velocity has doubled, (2) The angular velocity is 4 times faster, (3) The rotational kinetic energy is 4 times higher. (4) The required centripetal force is 8 times stronger.
You can examine and modify this simulation if you have EJS installed by right-clicking within the plot and selecting "Open EJS Model" from the pop-up menu item.
The Angular Acceleration of a Contracting System model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_nl_teunissen_angular_acceleration.jar file will run the program if Java is installed.
