Distance time graphs

A distance-time graph is a visual representation that shows how the distance traveled by an object changes over time.

A horizontal line indicates that the object is stationary (not moving).

A straight diagonal line represents constant speed; the object is moving at a steady pace.

A curved line indicates that the object is accelerating or decelerating.

If one line crosses another line, it indicates that the object represented by the line that rises has overtaken the other object.

Speed is the rate at which an object covers distance, while velocity includes both speed and direction.

Acceleration is the rate of change of velocity of an object over time.

A steeper slope indicates a higher speed; the object is moving faster.

A downward slope indicates that the object is returning to the starting point.

Speed = Distance / Time.
