Solving Atwood Machine Lab: Determining Acceleration

Click For Summary
The discussion focuses on determining the acceleration of an Atwood machine using known weights and distances, but participants express confusion about applying the relevant equations. The group has collected data but struggles to understand how to calculate acceleration. A link to a Wikipedia article on Atwood machines is suggested as a potential resource for clarification. With additional peer support and the provided link, the group gains a better understanding of the dynamics involved. Overall, the discussion highlights the challenges faced in applying theoretical concepts to practical lab work.

Homework Statement


Useing atwood machine, determine acceleration, knowing weight of mass to be pulled and mass pulling, distance mass travels, and information provided by photogate[which we don't understand what exactly this information is]

Homework Equations


Unknown...

The Attempt at a Solution


Please help. My lab group is at a complete loss on the application of this section, we have no idea where we need to start. We have our data collected, but we don't know how acceleration can be found.
 
Physics news on Phys.org
With a combination of that site and peer help we were able to figure out what to do. I think we may have a little better understanding on dynamics. Thank you.

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
