So for this instance on my lab report, should i record down because it doesn't perfectly obey hooke's law?

I have been conducting a lab to find the force of a spring by calculating the oscillatory motion of the period. Each time i added a mass, i gained a higher spring constant, but on the 250g i ended up losing spring constant. I was wondering if anyone know why, or if i have done something wrong...

So if I was to redo my lab. And I would have to pull the spring how would I measure the time?

So if I don't pull it and let it hanging it doesn't count as oscillatory motion?

Hi, i started to learn oscillatory motion today, and my teacher didn't teach us very well...and he told us that we were to conduct a oscillatory motion lab. So, me and a couple of other friends conducted a spring not moving that was hanged vertically and just calculated the displacement of the...

Yea I usually have a tutor in university to help me out but this was a bit of urgent for the lab

Okay got it thanks guys yea my classmates aren't really getting it either we're not learning much from the teacher since its his first year in physics 20 but much appreciated the help

So I would multiply the mass and acceleration and add up the uncertainty correct?

Yea I know how to add but how do I know which uncertainties to add and which to leave separate?

Nope I am afraid I haven't learned that propagation yet. But how would I find the uncertainty for the timer? Even If I know there is a 5% in error?

f = ma

Yea I got the notes for that but why would I combine them?

I am currently working on my physics lab report, and my question is "What effect does the mass have on the change of acceleration?" The lab currently consist of two pulleys hanging on each end balancing weighing 100kg, i continuously add 10kg for each turn, i then record the time of the...

I am needing assistant on my physics homework. I have received the answer of 0.6m/s2 and 0.9ms/2 for the answers but when i check my key that the answer provided it is 3.6m/s2 and when i check over the work they provided it doesn't make sense to me at all. They got the answer of 3.6 by adding...

Hi, i am doing physics 20 and i am still quite new at this stuff. I have a base understanding of how the mass affect the acceleration but i can't find a way to explanation of why the the mass affects the acceleration by making it faster or slower of a pulley for my lab like this one...
