Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
We begin by studying the type of force that underlies the simplest oscillations and waves. We will then expand our exploration of oscillatory motion and waves to include concepts such as simple harmonic motion, uniform circular motion, and damped harmonic motion.
Oscillatory Motion. 4.1 The Important Stuff. 4.1.1 Simple Harmonic Motion. In this chapter we consider systems which have a motion which repeats itself in time, that is, it is periodic. In particular we look at systems which have some coordinate (say, x) which has a sinusoidal dependence on time.
13.1 - Simple Harmonic Motion Oscillations Free oscillations occur when no external force is continuously acting on the system, so its energy remains constant. The system will oscillate at its natural frequency . Examples of systems which experience free oscillations are:
Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing. Observe the energy in the system in real-time, and vary the amount of friction.
