This shows a constant speed. The slope on a distance time graph represents the speed.

We calculate speed by the equation: speed m/s= distance traveled (m) DIVIDED BY time taken (s)

Velocity= speed in a given direction.

Velocity

Velocity= 

Velocity= DISTANCE / TIME.

acceleration is its change of velocity per second. unit= m/s2

any object with a change of velocity is accelerating 

Acceleration= change in velocity (m/s) / time taken for change(s)

the slope of the line on a velocity time graph represents acceleration.

To find out the distance traveled on a velocity time graph, ypu use thr area under the line. for example a car was traveling at a velocity of 20 m/s for ten seconds. so you multiply it to find out the distance traveled. i.e 200m 

distance when it acclerated would be 0.5 x height x base of triangle.
