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)
