A type of friction that acts on objects moving through air.

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

How does mass affect motion?

Back

More mass means more force is needed to change its motion.

Front

What is a distance/time graph?

Back

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

Front

What happens when you apply force to an object?

Back

It can start moving, stop moving, or change direction.
