Front

You can show the motion of an object on a line graph in which you plot distance against

Back

time.

Back

Motion is the change in position of an object over time.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

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

Back

A flat line indicates that the object is at rest.

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).
