Distance time graphs

Front

What does a constant speed look like on a distance-time graph?

Back

A straight, diagonal line that moves away from the origin.

Front

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

Back

The object is stationary (not moving).

Front

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

Back

By calculating the slope of the line; steeper slopes indicate higher speeds.

Front

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

Back

The object is accelerating or decelerating.

Front

If a distance-time graph shows a line going upwards, what does that mean?

Back

The object is moving away from the starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If an object travels 30 meters in 10 seconds, what is its speed?

Back

3 meters per second (m/s).

Front

What does the area under a distance-time graph represent?

Back

It does not represent anything; area under a speed-time graph represents distance.

Front

What does a line that slopes downwards indicate on a distance-time graph?

Back

The object is returning to the starting position.

Front

What is average speed?

Back

Total distance traveled divided by total time taken.
