What is a Distance - Time Graph?

A distance - time graph shows
how an objects distance (how far it has gone) changes with time.

The picture below shows a distance - time graph
for an object that is stationary.

The above graph shows an object which is not moving (at rest).
The straight horizontal line shows that its distance
stays the same as time goes by because it is not moving.

The picture below shows a distance - time graph
for an object with a constant velocity.

The straight line sloping upwards in the graph above
shows that the objects distance increases as time goes by.
The object has velocity because it is moving.
The straight line shows that it is a constant velocity.
The gradient (slope) of the line shows how fast the object is going.
The greater the slope, the bigger the velocity is.
Compare this with the velocity - time graph for constant velocity.
