Question | Answer |
Frame of reference | an object which is used to measure changes in position |
Displacement | change in position from the starting point |
Velocity | the measure of rate of movement of an object. Includes direction of motion. |
Average Velocity | total displacement divided by total time. (includes direction) |
Average Speed | distance traveled divided by total time. (does not include direction) |
Slope | rise over run on a graph. Divide the change in the y coordinates by the change in the x coordinates |
Instantaneous Velocity | velocity of an object at a certain moment in time. |
Instantaneous Speed | the number given to you by your car’s speedometer. |
Acceleration | Rate at which velocity changes over time. Can be positive or negative. It is determined by a change in speed, direction, or both. |
Free Fall | Motion of a body when the only force acting on it is gravity. |
Air Resistance | Friction created by air that slows the acceleration of an object in free fall. |
Terminal Velocity | The constant speed an object reaches when falling through a medium. It does depend on mass, shape, and size. |
