Is a crowbar a force multiplier, a distance multiplier, or both?

A crowbar is classified as a force multiplier. This tool leverages the principles of leverage, which allow the user to apply a smaller input force to lift or move a heavier object. The design of the crowbar includes a long lever arm, which increases the distance over which the input force acts, thereby allowing the force exerted at one end to be applied to the load at the other end with greater effect.

While a crowbar does affect distance in the sense that it may allow for the application of force over a longer lever arm, its primary function is to amplify the amount of force applied. In doing so, it allows individuals to accomplish tasks that would be difficult or impossible with their own strength alone. Therefore, the primary reason for classifying a crowbar as a force multiplier is its ability to increase the effective force applied to an object, making it easier to lift or move it.
