| Dependent variable | its what you measure: the information you put in the data table * changes the independent variable * does not depend on anything else (stands alone) |
| Inertia | 1) the tendency off all objects to resist a change in motion 2) the more mass an object has the more inertia it has |
| Newton's 1st law of motion | effect of balanced and unbalanced forces on an object at 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 v.s. Weight | Mass: does not change with location Weight: it does change with location. A measure of the force of gravity |
| Frame of Reference | a framework that is used for the observation and mathematical description |
| Assumption | a thing that is accepted as true or as certain to happen, without proof. |
