speed equals distance divided by

time

When you know both the speed and direction of an object you know

velocity of the object

the steepness of a line on a graph is called the

slope

If you know a car traveled 200 kilometers in 4 hours, you can determine its

speed

When an objects position relative to another object is changing,

it is in motion

A place or object used for comparison to determine if an object is in motion is called

a reference point

average speed is

the total distance divided by the total time

vector quantities measure

magnitude and direction

Scalar quantities measure

magnitude only

In a distance v time graph a steep slope means

fast!!!

stopped

stopped

In a time v distance graph, time is usually on the

x-axis

Changes in velocity may be due to changes in speed and/or

direction

Instantaneous speed is the rate at which an object is moving

at a given instant in time

The total length of the actual path between two points is

distance

The total length and direction of a straight line between two points is

displacement
