The force applied to a simple machine is called effort force. The amount of work a simple machine can do is based on effort force multiplied by the distance a machine moves or lifts an object.Continue Reading
Simple machines with longer distance capabilities require less effort force to move an object. For example, pushing a box up a ramp that is long with a gradual incline requires less effort force compared to pushing a box up a ramp that is short and steep.
Simple machines create a mechanical advantage by converting a small effort force into a large output force. For example, the small effort force applied to a jack handle creates a large output force capable of lifting the back end of an automobile.Learn more about Motion & Mechanics
