Objective:
To demonstrate momentum and impulse.
The second law of motion states that the force “F” applied to a body of mass “m” that undergoes an acceleration “a”is given by F = ma.
Apparatus:
- Impulse and momentum box

Method:
A cardboard box with a hole on one side and a plastic diaphragm on the other side is used. When the diaphragm is impacted a pulse of air is accelerated from the hole and its force is felt. To actually see the moving pulse of air, the box may be filled with smoke through the hole.
