|
reference point |
the starting point you choose to describe the location or position of an object |
|
|
position |
an object's distance and direction from a reference point |
|
|
acceleration |
a measure of the change in velocity during a period of time |
|
|
average speed |
total distance/total time |
|
|
displacement |
difference between the 1st position and the final position of an object |
|
|
distance |
the measured amount of a distance you traveled |
|
|
changing speed |
speed at a specific instant in time |
|
|
constant speed |
the rate of change of position in which the same distance is traveled each second |
|
|
instantaneous speed |
when the speed of an object is constantly changing |
|
|
speed |
a measure of the distance an object travels per unit of time |
|
|
velocity
` |
the speed and the direction of a moving object |
|
|
motion |
process of changing position |
|
|
distance vs. time graph |
speed is shown as a straight line slowing down - downward curve stopping - horizontal line speeding up - upward curve |
|
|
speed vs. time graph |
at rest - horizontal line constant speed - horizontal speeding up - slanting upwards slowing down - slopes downward to the right shows how speed is changing over time |
