I did measure the period for 10 oscillations (10T) and I used a regular timer so there are several errors here. Again thank you !

Well I'd say the oscillating-method is more trustworthy, since it only depends on one variable (mass) that can be measured more accurately than the elongation x in F=kx. But i don't know if this is true?

My question is if there is an alternative, maybe better, way of doing this?

Thanks! Yeah I just performed one measurement with each method.

During an experiment, using Hooks law resulted in a spring constant of 7,8N/m while for the oscillation-method the constant was 8,6N/m. Could someone help me to clarify whay they differ and which vlsue is the correct one.

Well, in terms of functionality I guess the method works since I managed to create a temporary magnet out of the wrench that in turn influenced the iron nail. Pros with this method, I guess, would be that it is easy to perform. The cons would be that it's only a temporary magnet. (Not sure about...

So basically what I had to do was: 1. take a Allen wrench and let it come in contact with an iron nail. Nothing happened here. None of the objects are magnetic. 2. take the Allen wrench and let it touch the North end of a magnet. Then let the wrench come in Contact with the iron nail. Here the...

Thanks!

Thanks!

Well I haven't measured anything directly, everything is assumed. So I have to evaluate the assumed values. For instance I assumed that the length x is 0.32m. But this length could be longer or shorter depending on: 1. friction 2. how fast/hard the marble is set in motion, 15cm from the edge...

Think that is a bit advanced for me (doing high school physics :) )

Friction from the table and air. And also gravity

This is how I think the set up of the lab should look like. I've decided the height to be y=1,5m. The length x is assumed to be 0.32m. where Voy =0m/s the time it takes for the marble to drop 1,5m is 0,55s the inital velocity of the marble is around 0,47m/s I Think I have the...

thanks!

Was just wondering if someone could take a look at my calculations and see if I've done them correctly.
