1. Force is a pushing or pulling action by one object against another. When force is applied and movement occurs, such as with these bicycle pedals, work is performed by moving the bicycle from one location to another. Torque is a measure of the ability of a force to cause twisting or rotation. An engine's crankshaft, nuts and bolts when they are tightened or loosened, and bicycle pedal crank sets rotate around an axis. The rotational or twisting force of these items is called "torque," which is measured in "pound-foot" units of force times the distance from the axis of rotation.
