| Design | ) To plan out in systematic, often graphic form. To create for a particular purpose or effect. Design a building. (noun) A well thought-out plan. |
| Engineering | Applying scientific and mathematical principles to practical ends such as the design, manufacture and operation of efficient and economical structures, machines, processes and systems. |
| Force | A push or pull on an object |
| Inclined plane | A simple machine that raises an object to greater height. Usually a straight slanted surface and no moving parts, such as a ramp, sloping road or stairs. |
| Lever | A simple machine that increases or decreases the force to lift something. Usually a bar pivoted on a fixed point (fulcrum) to which force is applied to do work |
| Mechanical advantage | ,An advantage gained by using simple machines to accomplish work with less effort. Making the task easier (which means it requires less force), but may require more time or room to work (more distance, rope, etc.). |
| Pyramid | A massive structure of ancient Egypt and Mesoamerica used for a crypt or tomb. The typical shape is a square or rectangular base at the ground with sides (faces) in the form of four triangles |
| Pulley | A simple machine that changes the direction of a force, often to lift a load. Usually consists of a grooved wheel in which a pulled rope or chain runs |
| Screw | A simple machine that lifts or holds materials together. Often a cylindrical |
| Simple machine | A machine with few or no moving parts that is used to make work easier |
| Spiral | A curve that winds around a fixed center point (or axis) at a continuously increasing or decreasing distance from that point. Tool |
| Tool | A device used to do work. |
| Wedge | A simple machine that forces materials apart. Used for splitting, tightening, securing or levering. It is thick at one end and tapered to a thin edge at the other |
| Wheel and axle | A simple machine that reduces the friction of moving by rolling. A wheel is a disk designed to turn around an axle passed through the center of the wheel |
| Work | Force on an object multiplied by the distance it moves. W = F x d (force multiplied by distance). |
