|
Acceleration
|
The rate at which velocity changes
|
|
|
Average Speed
|
The total distance traveled divided by the time it takes to travel
that distance |
|
|
Constant Acceleration
|
A steady change in velocity
|
|
|
Distance
|
The length of the path between two points
|
|
|
Frame of Reference
|
A system of objects that are not moving with respect to one another
|
|
|
Free Fall
|
The movement of an object toward earth because of gravity
|
|
|
Instantaneous Speed
|
The rate at which an object is moving at a given point in time
|
|
|
Linear Graph
|
A graph in which the displayed data form is a straight line
|
|
|
Nonlinear graph
|
A graph in which the displayed data is a curved line
|
|
|
Relative Distance
|
A movement in relation to a frame of reference
|
|
|
Resultant Vector
|
The vector sum of two or more vectors
|
|
|
Speed
|
The ratio of the distance an object moved to the amount of time it moves
|
|
|
Vector
|
A quantity that has a direction assosciated with it.
|
|
|
Velocity
|
The speed and direction has an object is moving, measured relative to
a reference point |
|
|
Compare Distance and Displacement
|
Distance is the length between two points. Displacement is distance
that includes direction. |
|
|
Calculate Displacement
|
Calculate displacement by adding the numbers if they are in the same
direction. Subtract if they are in different directions. |
|
|
Interpret distance-time graphs
|
Slope of a distance time graph is velocity
|
|
|
Describe 3 changes in velocity (acceleration)
|
Changes in speed, changes in direction, or changes in both.
|
|
|
Interpret Speed Time Graphs
|
If it goes up the object is accelerating. If it goes down the object
is decellerating. The slope of of a speed time graph is acceleration |
|
