| Term | Definition |
|---|---|
| Speed | The rate at which an object's moves |
| Average Speed | Speed= distances divided by time/DISTANCE,TIME |
| Velocity | Tells the rate an object's moves and in which direction it moves ***Think of the air traffic controller |
| Acceleration | Change in velocity(speed and direction) of movement and direction of an object (Think of car) **a car going at the same speed but turning or going into a curve |
| Force | In science the push or pull between objects |
| Mass | The amount of matter making up an object |
| Independent variable | What you change in your experiment or its the variable that you are testing |
| Gravity | Its changes the independent variable |
| Inertia | 1) The tendency of all objects to resists a change in motion 2) The more mass an objects has the more inertia it has |
| Dependent Variable | It's what we measure: the information you put in the data table *Changes the independent variable *Does not depend on anything else (stands alone) |
| Newtonś 1st law of motion | Effect of balanced and unbalanced forces of an object at the rest and on an object in motion |
| Newton's 2nd law of motion | The amount of force needed to accelerate an object. It depends upon the mass of the object |
| Mass VS. Weight | Mass- Does not change location Weight- It does not change location. A measure of the force of gravity |
| Energy | |
| Assumption | |
| Balanced Force | |
| Unbalanced Force | |
| Vectors | |
| Resultant | |
| Frame of Reference | |
| unit for volume | cm |
| unit for liquid | mL |
