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.
