In: How would the period of a pendulum on earth differ from that on the moon?
Objective: Find out the relationship between period and length of a pendulum. Success criteria: to be able to explain the equation for the period of a pendulum
Lab: period of a pendulum Problem: what are the variables that affect the period of a pendulum? List possible variables Test possible variables From your data, determine what the variables are that affect the period of a pendulum. What are the relationships between the variables?
Now that weve determined what variables affect period… what is the relationship? Tα ? Tα L Tα 1/L Tα L 2 TαLTαL
Direct relationship: graph is a straight line Y α X
Inverse relationship Y α 1/X Plot the reciprocal to get a straight line.
Power relationship Yα X 2 Square the x axis values
Root relationship Y α X Plot the square root of the x values to get a straight line.
