Today you completed a lab to determine what and how quantities affect the period of oscillation for a mass on a spring.
No extra homework tonight, but this lab is due Wednesday.
We ended up with some hints on the board, so there is a picture of it below.
If you missed the lab or didn't get enough data at home, there is an online simulation here:
To use it you need to make sure the "friction" is set to zero, time is set to "real time" and the planet is "earth." Use the spring on the far right and change its k value by moving the "softness spring 3" slider. You will have to find the k for each "softness" level by hanging a known weight on the spring and measuring how far it stretches (tip: if you set the friction to "lots" for this part, it will keep the mass from bouncing and let you measure the stretch more easily). Then k = mg/x. Finally, you'll need more masses that the labelled ones provided, so I found the masses of the unlabeled colored masses for you: green = 70g, gold = 160g, red = 300g.
