Distance time graphs

A distance-time graph represents the relationship between distance traveled and time taken, showing how speed varies over time.

A horizontal line indicates that the object is at rest, meaning it is not moving.

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

A curved line indicates acceleration, meaning the object is speeding up or slowing down.

Speed is a measurement of how fast an object is moving, calculated as distance divided by time.

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

A steep slope indicates a high speed, meaning the object is covering a large distance in a short amount of time.

A gentle slope indicates a low speed, meaning the object is covering a small distance over a longer period of time.

A vertical line is not possible in a distance-time graph as it would imply infinite speed, which is not physically possible.

The speed can be determined by calculating the slope of the line on the graph, which is the change in distance divided by the change in time.
