Distance and Speed Time Graphs

Front

What is a speed-time graph?

Back

A speed-time graph is a visual representation that shows how speed changes over time.

Front

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

Back

A horizontal line indicates that the object is moving at a constant speed.

Front

What does a downward slope on a speed-time graph represent?

Back

A downward slope indicates that the object is slowing down or decreasing speed.

Front

What does an upward slope on a speed-time graph represent?

Back

An upward slope indicates that the object is speeding up or increasing speed.

Front

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

Back

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

Front

What does it mean when the speed is zero on a speed-time graph?

Back

It means the object is at rest and not moving.

Front

How can you tell if one object is faster than another on a speed-time graph?

Back

The object with the steeper slope is moving faster.

Front

What does the area under the speed-time graph represent?

Back

The area under the graph represents the distance traveled by the object.

Front

What is the difference between constant speed and variable speed?

Back

Constant speed means the speed does not change, while variable speed means the speed changes over time.

Front

What does it mean if a graph shows a flat line at the bottom?

Back

It indicates that the object is at rest for that period.
