|
acceleration |
the rate at witch an object changes its velocity |
|
|
acceleration due to gravity |
acceleration due to gravity in the absence of air resistance |
|
|
air resistance |
a friction like force that opposes the motion of objects that move through the air |
|
|
average acceleration |
average rate at witch an object changes its velocity shown by the slope of a velocity time graph |
|
|
change in velocity |
change that occurs when the speed of an object changes, or its direction of motion changes,or both; calculated by subtracting the initial velocity from the final velocity |
|
|
constant acceleration |
velocity changing at a constant rate |
|
|
deceleration |
acceleration that is opposite to the direction of motion; decrease in the speed of an object |
|
|
gravity |
attractive force between two or more masses; causes objects to be pulled toward the center of earth |
|
|
velocity time graph |
a graph of an objects velocity during corresponding time intervals |
