Speed/Time Graphs

Front

What does a horizontal line on a speed/time graph represent?

Back

Constant speed.

Front

What does a line with a positive slope on a speed/time graph indicate?

Back

The object is speeding up.

Front

What does a line with a negative slope on a speed/time graph indicate?

Back

The object is slowing down.

Front

What does a flat line at the bottom of a speed/time graph represent?

Back

The object is at rest.

Front

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

Back

The speed is represented by the height of the line on the graph.

Front

What does a steeper slope on a speed/time graph indicate?

Back

A faster speed.

Front

What does a line that curves upwards on a speed/time graph represent?

Back

The object is accelerating at an increasing rate.

Front

What does a line that curves downwards on a speed/time graph represent?

Back

The object is decelerating.

Front

If two lines on a speed/time graph are parallel, what does that indicate?

Back

Both objects are moving at constant speeds.

Front

What is the significance of the area under the line on a speed/time graph?

Back

It represents the distance traveled.
