| A | B |
|---|
| Acceleration | The time rate of change of an object's velocity |
| Accuracy | An indication of how close a measurement is to the true value |
| Air Resistance | The drag that air produces on objects traveling through it |
| Angle of a vector | The counterclockwise angle between a two-dimensional vector and the positive x-axis. The angle tells you the direction of the vector. |
| Average acceleration | The acceleration of an object over an extended period of time |
| Average velocity | The velocity of an object over an extended period of time. |
| Derivation | A process by which one starts with a known fact, such as an equation, and uses logic and reasoning to come up with a different fact, such as another equation. |
| Displacement | The change in an object's position |
| Factor-label method | Method used in this course to convert between units |
| Free fall | The motion of an object when it is falling solely under the influence of gravity. |
| Instantaneous acceleration | The acceleration of an object at one moment in time |
| Instantaneous velocity | The velocity of an object at one moment in time |
| Position | A vector quantity that describes where an object s relative to a reference point. |
| Precision | An indicatin of the scale on the measuring device that was used. |
| Reaction time | The time elapsed between recognizing an event and reacting to it. |
| SI units | System that contains the standard metric units used in science |
| Scalar quantity | A physical measurement that doesn't contain directional information. |
| Significant figure | A digit in a measurement that is wither non-zero, a zero that is between 2 significant fug. or a zero at the end of the number & to the right of the decimal. |
| Slope of a graph | A measure of how steeply a curve is rising or falling. |
| System Internationale | (SI) System that contains the standard metric units used in science. |
| Terminal velocity | The velocity a falling object has when, due to air resistance, its acceleration is reduced to zero. |
| Vector quantity | A physical measurement that contains directional information |
| Velocity | The time rate of change of an object's position |
| Slope of a graph | Calculated by taking the change in the y-coordinate and dividing by the change in the x-coordinate. |
| Terminal velocity | This is the maximum velocity a falling object subject to air resistance can achieve. |
