Pivot interactives 6.1 Pendulum Investigation

Design a third experiment to find how a different characteristic of a pendulum (mass, length, or release angle) affects the period. 1. Use this data table and graph to record and analyze your data.

Describe your experimental design here. Include: c which quantities will you hold constant? c which quantity will you vary? 0 which quantities will you measure? Try to use the framework for writing an experimental procedure provided by the AP board (if you have forgotten, nd an AP video that shows it) BIU EEEEEE %llfx From the beginning, we will hold the length of the pendulum and the release angle constant. On the other hand, we must vary the mass in order to measure how a change in mass affects the period. Use balance to measure the mass of the pendulum bob and Mass should be measured with scale in grams (g). We have to measure the period. Period denes the time it takes the pendulum to make one full back-and-forth swing, so as the nger lets go bob, then the timer should be started and stopped when the bob hits the stand. Lastly, the experiment should be repeated three times, then get the average value of the period based on each length in order to reduce uncertainty and human errors. 3. Describe your results: 0 which quantities did you plot on the axes of your graph 0 how did you linearize the data (if needed} 0 the meaning of the slope and intercepts for your line 0 a statement of the relationship, "[variable A] is proportional to [variable B] Hint: Use the CER method where appropriate - Claim Evidence Reasoning BIQ 355523 @313: Even though some quanties of the period do not remain constant, the result shows that the mass of the pendulum bob does not matter with the period. It is because whatever the mass is, the acceleration of the pendulum bob, which is the gravitational force of 9,81m/sA2, remains constant, pulling the pendulum bobs with the same force. Seeing that amount of mass does not matter the period, mass is not proportional to the period. Score: Comments: 0/ 10 'does not matter'?? Not a good scientic sentence. You need to provide evidence for your statement - what on the graph shows you this? Is there a law or equation you can then reference to provide a reason for this
