This simulation, presented by the University of Colorado’s PhET, explores the forces at work when you try to push a filing cabinet. Charts show the forces, position, velocity, and acceleration vs. time.

This animation, provided by the University of Rhode Island’s physics department, explains the forces on a car and the stopping distance when brakes are applied so that no skidding occurs. The video also explains how to calculate the speeds at which a car can safely drive around a banked turn, taking the force of static friction into account.
