Pendulum

When you are done with you data tables and graphs, post them here

Purpose: The purpose of this experiment is to measure the change in frequency of a pendulum swinging versus the inverse of the length of string. This in turn allows us to determine if the slope of the graph will be equal to g/4p^2. Materials
 * 1)  Mass
 * 2)  String
 * 3)  Stopwatch
 * 4)  Life (Cereal)
 * 5)  Gatorade
 * 6)  Chai
 * 7)  Hanging mass device

Procedure:
 * 1) First we hung our mass from al long string that nearly brushed the ground, measuring 135cm
 * 2) Proceeded to pull the mass to the left 10° in relation to the perpendicular of the ground. ^
 * 3) Allowed mass to swing free of impedance for 50 swings all the while timing its pace.
 * 4) Shortened the string bit by bit repeating step 3 10 times in order to procure sufficient data.

Purpose: The purpose of this experiment is to measure the change in frequency of a pendulum swinging versus the inverse of the length of string. This in turn allows us to determine if the slope of the graph will be equal to g/4p^2. We are also venturing blindly into the world of physics in the name of the almighty one Materials

Procedure: ~Stevo~
 * 1) First we hung our mass from al long string that nearly brushed the ground, measuring 135cm
 * 2) Then we proceeded to pull the mass to the left 10° in relation to the perpendicular of the ground. ^
 * 3) We then allowed the mass to swing free of impedance for 50 swings all the while timing its pace.
 * 4) We then shortened the string bit by bit repeating step 3 10 times in order to procure sufficient data.
 * 5) We then led a troupe of weary men to the sub-basement computer lab to input our data into the central data point.
 * 6) This led to a new world disorder.

Teleri! Gee! Graph: Purpose & Procedure:

here is mine (drew)

PURPOSE: The purpose of the experiment was to determine the acceleration of a weight on the end of a pendulum due to gravity. MATERIALS: ·  1x 200g mass (with hook to attach string) ·  1x stopwatch ·  1.33m string ·  1x protractor ·  1x roll of tape PROCEDURE: 1. Hang the 200g mass from the end of a long string. 2. Attach the other end of the string to the table. 3. Tape the protractor to the table such that you can measure the angle of the string. 4. Pull the mass 10 degrees from perpendicular. 5. Let go. 6. With the stopwatch, measure the amount of time the pendulum takes to swing to its peak height on the opposite side, and record this time. 7. Repeat steps 3-5 fifty times (25 times in each direction). 8. Remove mass from the end of the pendulum and shorten the string by 10 cm, reattach mass to end of string, and record new length of string. 9. repeat steps 3-8 ten times.
