Speed & Distance Time Graphs

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually measured in miles per hour (mph) or meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What does a distance-time graph show?

Back

A distance-time graph shows how far an object has traveled over a period of time.

Front

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

Back

A flat line indicates that the object is stationary (not moving).

Front

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

Back

A steep line represents a high speed; the steeper the line, the faster the object is moving.

Front

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

Back

A curved line indicates that the object is accelerating or decelerating.

Front

What is a head start?

Back

A head start is when one runner begins the race before the others, giving them an advantage.

Front

If a runner travels 20 miles in 10 minutes, what is their speed?

Back

Speed = 20 miles ÷ 10 minutes = 2 miles per minute.

Front

What does it mean if a distance-time graph has a downward slope?

Back

A downward slope indicates that the object is returning to the starting point.

Front

What is constant speed?

Back

Constant speed means the object is moving at the same speed throughout the entire time period.
