Final answer:
Simple machines make work easier by reducing the amount of force we need to apply to an object.
Step-by-step explanation:
Simple machines make work easier by reducing the amount of force we need to apply to an object. They can change the amount of force we exert and the distance over which we apply the force. In most cases, simple machines are used to reduce the amount of force we must exert to do work. While simple machines make work easier, they do not decrease the amount of work we have to do because the product of force and distance, which equals work, does not change.
