Speed and Velocity

Front

What are the axes on a distance-time graph?

Back

The x-axis is time and the y-axis is distance.

Front

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

Back

A steeper line shows a faster speed.

Front

What is instantaneous speed?

Back

An object’s speed at any particular moment.

Front

What does it mean if a swimmer's line on a graph is flat?

Back

The swimmer has stopped swimming.

Front

How can you determine if one object is moving faster than another on a distance-time graph?

Back

Compare the steepness of their lines; the steeper line indicates a faster speed.

Front

What is average speed?

Back

Total distance traveled divided by total time taken.

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).

Front

If a skateboarder is moving about twice as fast as a walker, what can be inferred about their speeds?

Back

The skateboarder's speed is greater than the walker's speed.

Front

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

Back

No movement; the object is stationary.

Front

What happens to the speed of an object if the distance increases but the time remains constant?

Back

The speed increases.
