Speed & Distance Time Graphs

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually measured in meters per second (m/s).

Front

What is a distance-time graph?

Back

A distance-time graph shows how the distance of an object changes over time.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving.

Front

What does a steep slope on a distance-time graph represent?

Back

A steep slope represents a high speed; the object is moving quickly.

Front

What does a gentle slope on a distance-time graph indicate?

Back

A gentle slope indicates a lower speed; the object is moving slowly.

Front

What does it mean if the line on a distance-time graph curves upwards?

Back

A curved line indicates that the object is accelerating.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of speed over time.

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line indicates constant speed.

Front

What does it mean if the speed-time graph slopes downwards?

Back

A downward slope indicates that the object is slowing down.
