Pendulum Test Review
1. Terms and Definitions
Bob
Pendulum
Length
Displacement
Amplitude
Frequency
Period
Cycle (vibration)
Kinetic Energy
Potential Energy Transformation of Energy
etc.
All of these words were defined in your notes!!
2. Pendulum Variables and Motions
Variables to know:
The variables that do and do not affect the frequency of a pendulum.
How does a change of length affect the frequency of a pendulum?
Longer?
Shorter?
How does the length change the period of a pendulum?
Longer?
Shorter?
The ones we studied in the Pendulum Lab.
Motion: Know positions forPotential Energy and Kinetic Energy
Greatest and least acceleration
What constitutes a cycle or vibration
Comparison between displacement and amplitude.
3. Solving Problems: Know how to use the triangle.
f= Frequency
T= Period
1
f= cycles
seconds.
T= seconds OR
cycle.
T= _1_
f
f
4. Graphing: Review lab graphs
Accurately draw BEST FIT relationship lines.
Be able to find Frequency from length or length from frequency.
Be able to analyze your graph using the Best Fit relationship line.
5. Acceleration of Gravity: Go over sheet. Be able to use formulas.
1. Calculate frequency of a pendulum cycles/sec. or f= 1/t
2. The “g” or acceleration due to gravity. g=L x (2Π x f)2
3. % Error = Difference between Ideal and experimental x 100
Ideal
