1. Simple machine - B. basic mechanical devices that change the direction or amount of a force needed to lift a load or do work
2. Mechanical force - D. forces that involve contact with another object
3. Mechanical advantage - C. a ratio of the resistance force to the effort force
4. Inclined plane - F. a type of simple machine with a smooth slanted surface, reducing the force needed to do work
5. Pulley system - A. a type of simple machine with a rope or chain that wraps around a wheel, reducing the force needed to lift a heavy load
6. Lever - E. a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
