Distance-Time Graphs

Front

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

Back

The object is at rest.

Front

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

Back

The object is moving at a constant speed.

Front

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

Back

The object is accelerating.

Front

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

Back

Speed is calculated as the change in distance divided by the change in time (slope of the line).

Front

What does a steeper line on a distance-time graph mean?

Back

The object is moving faster.

Front

What does a flat line followed by a steep line indicate?

Back

The object was at rest and then started moving quickly.

Front

If a distance-time graph shows a line that goes back towards the origin, what does that mean?

Back

The object is returning to its starting position.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

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

Back

The object is returning to its starting point.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
