| aerodynamic | Able to move through the air with as little air resistance as possible. |
| air resistance | The force on a vehicle as it moves through the air. |
| analyze | To study something by breaking it down into simpler parts. |
| axle | A bar or shaft on which a wheel turns. |
| blueprint | A detailed plan or drawing that shows how something is designed. |
| classify | To group things together because they share one or more properties. |
| conclusion | A decision that is base on observations or on a study of data. |
| constant | A condition that is not changed in a scientific experiment. |
| controlled experiment | A scientific investigation in which one variable is changed and all the others are kept the same. |
| cost-effective | Able to produce the best results for the least money. |
| data | Information, such as that gathered during an experiment. |
| drag | Force that opposes the forward movement of a vehicle. |
| dynamics | The part of physics that deals with how things move and the forces that change their motion. |
| energy | The ability to do work or make something happen. |
| evidence | Something that offers proof. |
| experiment | A procedure that is carried out to investigate a scientific question. |
| force | A push or pull. |
| friction | Force that resists movement between two objects that are touching. |
| gravity | A force of attraction between two masses. The strength of this force is dependent on the mass of each object and their distance from one another. |
| hypothesis | A prediction about how something works or how two variables are related. |
| kinetic energy | Energy associated with motion. |
| laws of motion | Three laws, formulated by Sir Isaac Newton, that describe how objects move in relation to the forces acting on them. |
| mass | The amount of matter an object has. |
| mean | The mathematical average of a number of measurements. |
| median | The middle value of a number of measurements. |
| mode | The value occurring the most frequently in a series of measurements. |
| opinion | An expression of how one thinks or feels about something based on presonal views, not necessarily on facts. |
| pattern | A repeating arrangements of shapes, colors, numbers, or other things. |
| potential energy | Stored energy that can be released to become other forms of energy. |
| prototype | An original model or design. |
| recursive testing | Retesting and revising a product: part of the technological design process. |
| speed | A measure of how fast something is moving. |
| technological design | The process of designing and building products and ststems to meet human needs. |
| template | A set pattern, mold, of form. |
| tension | The force exerted by a stretched object, such as a spring. |
| three-view drawing | A diagram, showing top, side, and front views. |
| variable | An element in an experiment that can be changed. |
| weight | A measurement of how heavy something is. |
