B Suggestions for Internal Assessment Project on Young's Modulus

AI Thread Summary
The discussion focuses on conducting an Internal Assessment (IA) in IB physics centered on Young's modulus using stretchy candy snakes as the material. Key considerations include determining whether the stretchy snakes exhibit linear elasticity and the feasibility of designing an experiment to test this. Participants suggest outlining the necessary components of the experiment, such as measuring force and extension. The inquiry emphasizes the importance of understanding the material properties and the experimental approach. Overall, the project aims to explore the relationship between stress and strain in a practical context.

Hi. I am in the IB and am looking at doing a physics IA (internal assessment) on Young's modulus on an elastic material. I was thinking of doing it on the the stretchy snakes like the candy. What would I need to cover in this?
 
Physics news on Phys.org
Is a stretchy snake linearly elastic?
 
Maybe it's a great idea to figure this out by doing an experiment? That shouldn't be too difficult.
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
