Homework Statement I'm doing an EPI on horizontal circular motion and for one test the independent variable is mass and I need to control the velocity by using the 2πr/T formula. So I know how to use the forumula to find an unknown but how do I use it for two unknowns (r and T). Is there a...

Ok so the first paragraph was helpful thanks I don't understand the second paragraph... what does sigma mean? but I'll figure it out. Thanks so much :)

Hmm ok, I agree that it'll be better to talk about it in the discussion but i don't understand what you mean about my uncertainties. I'm a bit confused, what uncertainties are you suggesting I factor in? Thanks

Here's what it says on the project sheet: Sorry I couldn't be bothered typing it up So uncertainties I have are that: 1. some energy is used to bend the rod (need to work out how much) 2. Angle is slightly off because the rod is bent (I might just give a rough estimate and be done with...

Here's a picture of it: The force sensor reads about 7.5 N but it feels like a lot more than that. Would this type or spring use Hooke's law? I thought that was only for compression and stretch. I'm only investigating one mouse trap and one spring. I just need to graph the angle vs...

Sorry this isn't really intro to physics, it's high school physics... I'm investigating the force vs angle of a mouse trap and I need to talk about the uncertainties one thing is that the lever (hammer/arm/part that hits the mouse) bends. So the angle isn't very accurate. What formula do I...
