WebGears work to change the direction of motion. When you turned the big gear one way, the little gear turned the other way! Gears also change speed of motion. When you turn the big gear slowly, the smaller gear turns faster. This helps save energy, because you don’t have to work as hard to turn the big one slowly as if you had to turn the small ... Simple machines make work easier. Simple machines do not change the amount of work it takes to move an object, but they decrease the amount of force necessary to do the work by increasing the distance the object travels. Remember, work is a product of force and distance, so increasing the distance … See more A force is a push or a pull.
