Block of Wood on a String, 1C10.21

Topic and Concept:

Motion in One Dimension, [:MotionIn1D#Velocity: 1C10. Velocity]

Location:

Cabinet: [:MechanicsCabinet:Mechanic (ME)]
Bay: [:MechanicsCabinetBayB5:(B5)]
Shelf: #2

Abstract:

A wood block with attached string is pulled horizontally across a table at constant velocity in front of a meter stick. The time interval of the displacement can be measured using a stopwatch so that the velocity can be calculated.

Equipment	Location	ID Number

Blocks of Wood on a String	ME, Bay B5, Shelf #2
DMM or Multipurpose Timer	WS, Bay B1, Shelf #2
Meter Stick	ME, Bay B1, Shelf #2

Important Setup Notes:

Setup and Procedure:

Place a meter stick on the lecture bench.
Position the block such that the front face of the block is in line with the edge of meter stick.
Hook up the [:Table DMM-Timer:DMM] or [:MultiPurposeCounter:multipurpose meter] in stopwatch mode. Click the respective link for setup/operation information.
Begin to pull the block with constant force parallel to the meter stick. Maintain that force until the front face 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 proper equation: v = (x_f-x_i)/(t_f-t_i).

Cautions, Warnings, or Safety Concerns:

Discussion:

Discuss the physics behind the demonstration, explaining some of the various steps of the demonstration when appropriate.
