|
speed equals distance divided
|
time
|
|
|
when you know both the speed and direstion of an object, youprobably know the
|
average speed of the object
|
|
|
you can show the motion of an object on a line graph in which you plot distance againt
|
time
|
|
|
the rate at which velocity changes is called the
|
acceleration
|
|
|
if speed is measured in kilometers per hour, the unit of acceleration is
|
kilometers per hour per hour
|
|
|
average speed is
|
the total distance traveled divided by the total time
|
|
|
on a graph showing distance versus time, a horizontal line represents an object that is
|
not moving at all
|
|
|
it is rare for any motion
|
to staty the same for very long
|
|
|
if te speed doe NOT CHANGE the object traveling is at a
