A conical pendulum can be constructed by attaching one end of a string to some type of overhead support such as a door frame, ceiling, or other support. Then the other end of the string is attached to a reasonably dense object that will not be extensively impacted by air resistance. Set the object into circular motion by giving it a push tangent to the circle to establish horizontal circular motion. This may take a few practice runs to perfect.

Materials:

1. String
2. Method to support the string.
3. Reasonable dense object to tie to the string.
4. Protractor
5. Ruler/Meter Stick (Measure in meters to be dimensionally consistent.)
6. Spring Scale (Measure in Newtons to be dimensionally consistent.)
7. Stopwatch

Procedure:

1. Draw the free-body diagram for the object undergoing circular motion in a conical pendulum. It should include tension (T) and gravity (mg).
