This interactive simulation allows students to explore the motion of two blocks oscillating on two horizontal springs, and compare those motions to that of a simple pendulum. Users can set a variety of values: mass, initial position, length and initial angle of the pendulum, and damping strength. Motion may be stepped or paused. Real-time graphs of motion, energy, and forces may be viewed or hidden. The author also provides a set of suggested activities to accompany the simulation.
This applet was created with EJS, Easy Java Simulations, a modeling tool that allows users without formal programming experience to generate computer models and simulations.
