Outlines for Atwood’s Machine experiment

A.

  1. Do procedure 1 & 2, (put 185 grams on one side and 165 grams on the other side.)

    2. and print one sample table of data.

  2. Print out “Displacement vs. Time” graph.
  3. (if necessary) Drop data & print out the improved graph.
  4. Print “Velocity vs. Time” graph & find the acceleration.

B.

Total Mass

m2 + m1 ( )

Mass Difference

m2 – m1 ( )

Measured

a ( )

Plot “ a (measured) vs. m2-m1 “ and find g=?

(Hint: slope = g/(m2 + m1) )

E. 

          1. Discuss your results as much as possible.

2. Answer at least two questions. (If you have time, you can answer all.)
