Interpreting Graphs

How does the slope of a distance time graph relate to speed

The slope is the speed so a steeper slope means faster speed and shallower means slower

What does a flat line mean on a displacement time graph

The object is stationary and not moving

What does a line returning to zero mean on a displacement time graph

The object is returning to its starting point

How do you find maximum displacement on a graph

Look for the highest point the line reaches on the y axis

How do you know exactly when an object starts returning home on a graph

It is the point where the line changes direction and starts going back down towards zero

What kind of movement is a flat horizontal line on a distance time graph

The object is stationary or stopped

How do you visually tell which object covers the most distance in the least time

It is the line with the steepest slope because it has the fastest speed
