Question

This question refers to the passage and the illustration. A simple machine decreases the amount of force needed to do work by changing the size, direction, or speed of a force. Because machines conserve work, an increase in output force comes at the expense of a decrease in output distance. An increase in output distance comes at the expense of a decrease in output force. Inclined plane: a flat slope or ramp that multiplies force. An inclined plane decreases the amount of force needed to lift an object by increasing the distance the object moves. Wedge: an inclined plane that moves. A wedge mu
