| A glider on a level air track is pushed giving it a velocity which remains roughly constant on the low-friction surface. A timer together with a known displacement can be used to measure the velocity. | With a stopwatch, measure the time it takes to pull a wood block across a table at constant velocity in front of a meter stick. |

Important Setup Notes:
- N/A
Setup and Procedure:
- Place a meter stick on the lecture bench.
- Place the edge of front of the block at the beginning of the meter stick.
- Hook up the DMM or multipurpose meter in stopwatch mode. Click the respective link for setup/operation information.
- Begin to pull the block with constant force and maintain that force until the leading edge of the block makes it to the end of the meter stick.
- Have someone run the stopwatch beginning timing at the start of motion and ending when the block travels 1 m.
The velocity can be calculated using the equation for velocity: v = (xf-xi)/(tf-ti).
Cautions, Warnings, or Safety Concerns:
- N/A
Discussion:
Discuss the physics behind the demonstration, explaining some of the various steps of the demonstration when appropriate.
