This simulation encourages the exploration of the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Students can create an applied force and see how it makes objects move and change friction and see how it affects the motion of objects. The PhET Interactive Simulations project from the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
