### Work

This is the product of the force or effort needed to move a load multiplied by the distance it was moved.

### Screw

This is a simple inclined plane type machine that consists of a spirally threaded cylindrical rod that engages with a similarly threaded hole.

### Pulley

This is a small wheel with a grooved rim through which a rope of chains run. It changes the direction of a pulling force and combinations of these simple machines increase the force applied for lifting an object.

### Gear

This is a toothed wheel that engages another toothed mechanism in order to change the speed or direction of transmitted motion.

### Distance

This is the gap or measurement between two location.

### Lever

This is a class of rotating machines or devices in which effort applied to one part produces a useful movement at another part. They are used for moving of lifting loads.

### Force

This is an influence that produces a change in an object.

### Lever

This simple machine is a rigid bar that pivots on a fulcrum to move or lift a load.

### Inclined Plane

This simple machine is a slope or ramp that is used to lift a load. It trades distance for force

### Wedge

This is a combination of two inclined planes that is if itself moved with force to cut apart or separate an object.

### Wheel and Axel

This is a class of rotating machines or devices in which effort applied to one part produces a useful movement at another part. They are used for moving or lifting loads.
