Period and Frequency of The Pendulum

Question

I. QUESTION

What does the period of a pendulum depend on? What does the period of a pendulum not depend on? Mass? Length? Amplitude?

What is the relationship between the period and Mass? Length? Amplitude?

II. THEORETICAL

Physics concepts used in this lab

1. Write paragraph describing concepts:
2. Period
3. Frequency
4. Amplitude
5. Show equations used for concepts
6. Number equations
7. List variables in each equation showing what each means and units used.
8. Note: Number each equation, use “insert equation” in Google Docs for equations. You can also use Insert/Special Characters/Symbol/Math and Format/Subscript or Superscript. 

 Here’s some examples to show you what these should look like:

E=mc² (1)

E = energy (J)

m = mass (kg)

c = speed of light (m/s)

 

v = ∆x/∆t (2)

v = velocity (m/s)

∆x = displacement (m)

∆t = time (s)

1. Tell the reader how these concepts relate to this lab.

III. EXPERIMENTAL

What you did in your experiment...

1. List materials
2. Describe how you made your measurements
3. Sketch how you made your measurements

IV.     ANALYSIS

Taking measurements and reducing them

1. Show measurements (data) in an easy to read way (tables)
2. Show sample calculations
3. Graphs:
4. One graph per page
5. Include:
6. Title    
7. Label each axis           
8. Include units for each axis

V.      CONCLUSION

 

This will be a paragraph(s) that provide your claim, your evidence, and your reasoning. Here’s what we mean by claim, evidence, and reasoning:

 

Claim - A statement that answers the original question or addresses the purpose of the experiment. 

 

Evidence - Data that supports your claim.

 

Reasoning - Justification that links your claim to your evidence. This will be the physics concepts that show your evidence supports your claim. 

 

For each claim you make, you need to provide evidence for that claim, and the reason why that evidence supports your claim. If you have more than one piece of evidence for your claim, you need to provide the reason that piece of evidence supports your claim.

Answer 1

T= 2π√I/mgR where I is the moment of Inertia, m=mass, R = distance from pivot to center of mass ... I ≅ mR² thus T=2π√R/g and is not a function of mass
