The rate at which velocity changes is __________. | acceleration |
A decrease in speed is sometimes called | Deceleration or negative acceleration |
a type of motion where objects change direction but not speed is called | circular motion |
To determine acceleration of an object moving in a straight line, you must calculate | the change in speed per unit of time |
When a graph shows speed versus time as a slanted straight line the acceleration is | constant |
A graph of distance versus time for an accelerating object is | curved |
An object is in motion | when its distance from another object changes |
What is a reference point? | a place or object used for comparison to determine whether something is in motion. |
