Question | Answer |
Acceleration | The rate at which an object changes its velocity |
Air Resistance | A friction-like force that opposes the motion of objects that move through the air |
Average Acceleration | Average rate at which an object changes its velocity |
Average Velocity | The rate of change in position for a time interval |
Line of Best Fit | A straight line that most closely fits the general shape outlined by the graph |
Change in Velocity | Change that occurs when the speed of an object changes, or its direction of motion changes, or both (Vf- Vi) |
Deceleration | The acceleration that is opposite to the direction of motion; a decrease in speed of an object |
Displacement | The straight-line distance and direction from one point to another |
Distance (d) | A scalar quantity that describes the length of a path between two points or locations |
Gravity | Attractive forces between two or masses; causes objects to be pulled towards the center of earth |
Motion Diagram | A diagram that gives a picture of motion by showing an object's position at given times |
Position | A vector quantity that describes a specific point relative to a reference point |
Position-Time Graph | A graph of an objects position during corresponding time intervals; (time = x-axis, position = y-axis) |
Scalars | Quantities that have only a magnitude (no direction) |
Slope | A direction of a line on a graph, either horizontal (zero), slanting up ( positive), or slanting down (negative) Formula= rise/run |
Speed (v) | A distance of an object travels given a certain time interval divided by the time interval |
Time (t) | When an event occurs |
Time Interval | The difference between the final time and the initial time |
Uniform Motion | Traveling in equal displacements in equal time intervals |
Vectors | Quantities that have both a magnitude and a direction |
Velocity | The displacement of an object during a time interval divided by the time interval |
Velocity-Time Graph | A graph of an object's velocity during corresponding time intervals (time= x-axis, velocity= y-axis) |
Magnitude | Refers to the size of a measurement or the amount (number) you are counting |
