**Pendulum Lab**Working with Pendulums**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)**Copy this down!**This will help you greatly!**How does Mass affect frequency?**Test for mass. Change Mass, but keep amplitude and length same**How does Amplitude affect F?**Test for Amplitude. Change Amplitude, but keep mass and length same**How does Length affect FreQ?**Test for Length. Change Length, but keep amplitude and mass same**Groups!**Group 1 Group 2**Groups!**Group 3 Group 4**Groups!**Group 5 Group 6**Groups!**Group 7 Group 8
