Terms | Definitions |
|---|---|
 Friction | A force that resists movement between two objects that are touching. |
| Gravity | A force of attraction between any two masses. The strength of this force is dependent on the mass of each object and their distance from one another. |
| Inertia | The tendency of a moving object to stay in motion or a resting object to stay still. |
| Force | A push or a pull. This is also needed to make a moving object slow down, change direction or stop moving. |
| Potential Energy | Stored energy that can be released to become other forms of energy. |
| Kinetic Energy | energy associated with motion |
| Work | is only done when a force makes something move. ???? = Force X distance Work is measured in Joules. |
| Perpetual motion | Refers to movement that goes on forever. |
| Distance | How far something moves. |
| Speed | A measure of how fast something is moving. How far an object can go in a certain amount of time. |
| energy | Ability to do work. |
| unbalanced forces | initiate and influence movement. |
| balanced forces | When an object is at rest it is balanced. |
| momentum | The rate of acceleration. Momentum = Mass x Velocity |
| acceleration | is a vector quantity which is defined as the rate at which an object changes its velocity. An object is doing what if it is changing its velocity. |
| motion | the state in which one object's distance from another is changing. |
| technological design | The process of identifying a problem, creating a solution, evaluating the solution by testing, and then refining the design to improve performance is the essence of what? |
| template | a set pattern, mold or form. |
| technological drawing | Blue Print - detailed plan that you could use to recreate the same vehicle or design again. |
| velocity | The rate of change of position. |
| tension | a force exerted by a stretched object, such as a spring. |
| revolutions | the spinning of a wheel. One complete spin is equal to one revolution. |
| air resistance | The force of friction on a vehicle as it moves through the air. |
| propeller | The blades of a propeller act as rotating wings (the blades of a propeller are in fact wings or airfoils), and produce force. |
| axle | a bar or shaft on which a wheel turns. |
| drag | the force that opposes the forward motion of a vehicle. |
| laws of motion | Three laws formulated by Sir Isaac Newton, the describe how objects move in relation to the forces acting on them. |
| prototype | an original model or design. |
| steps in meeting a design challenge | 1. Plan 2. Build 3. Test 4. Evaluate |
| simple machines | machine with few or no moving parts that makes it easier to do work. |
