PENDULUM LAB
WHAT WE ARE DOING
• Using the information that you have learned about energy and what you have already done with lab writeups• Devise a procedure that looks at the variables
that affect each of the following parts of pendulous motion• Keep good notes!
I WILL BE LOOKING FOR…
• Prelab:• Definitions and Diagram (to follow—underlined
info)• Questions you are trying to answer (in your
groups today)• Variables that you are going to change (in your
groups)
• Lab Data• Data in tables please• Charts if necessary• Procedure that you followed• Any other observations
I WILL BE LOOKING FOR:
• Writeup:• Follow format in your cheat sheet (what we
have been doing all year!• Come up with the answers to the questions
that you were looking for!
DEFINITIONS:
• Bob• The mass that
swings
• Length• The distance from
the pivot point to the Center of the bob
• Amplitude• The vertical distance
pulled back from rest
DEFINITIONS:
• Cycle or Vibration• One full swing, over
and back
• Frequency (f)• The vibrations
(swings) made over a certain time.• F=cycles/time
DEFINITIONS
• Period of the pendulum• Time it takes for one
cycle to be completed• Measured in seconds• T=time/frequency(f)
