What is a distance-time graph?

Back

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

Front

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

Back

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

Front

What does a straight diagonal line on a distance-time graph represent?

Back

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

Front

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

Back

A steep slope indicates a faster speed; the greater the slope, the faster the object is moving.

Front

What does a flat line followed by a steep line on a distance-time graph represent?

Back

This represents a period of no movement (flat line) followed by a period of fast movement (steep line).

Front

How can you determine the speed of an object from a distance-time graph?

Back

Speed can be determined by calculating the slope of the line on the graph; speed = distance/time.

Front

What does a curve on a distance-time graph indicate?

Back

A curve indicates that the speed of the object is changing; it could be speeding up or slowing down.

Front

If a student walks 2.0 km in 30 minutes, what is their speed?

Back

Speed = distance/time = 2.0 km / 0.5 hours = 4 km/h.

Front

What does a vertical line on a distance-time graph represent?

Back

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

Front

How can you tell if an object has stopped on a distance-time graph?

Back

If the graph shows a horizontal line, it indicates that the object has stopped moving.
