Distance – Time (SPEED) Graph- shows how an object’s distance (how far it moved) changes with time.

Practice

A straight line equals constant speed (no change.)

A steeper line means a larger distance moved over time or a higher speed.

A flat line means there is no motion, the object

is at rest.

A curved line means speeding up or slowing down.

The steeper the graph, the faster the motion.A horizontal line means the object

is not moving, it is at rest

A downward sloping line means the object is returning to the start.
