My physics teacher said that the northern lights are the product of charged particles coming from the sun and interactign with our atmosphere. I believe he said that these are deflected by Earth's magnetic field and directed towards the North and South poles. When I look at pictures on this...

Yes the can is hollow, should I use mr2 instead? Anyways I believe static friction is something like μmg but how would I find the coefficient of friction? :(

Since I have a measured value for linear velocity I've been playing around with angular momentum, since L= Iω and L=mvr then Iω =mvr ω=mvr / I maybe I can do somethin with that but I would prefer to calculate a value for linear velocity. I found a formula that rearranges mgh = KE + rotational...

Exaclty, sorry I forgot to mention that.

Homework Statement I'm doing a coursework where I must find the angular acceleration of a rolling tin can using theoretical values. I have its mass and radius. I actually have experimental data so i have access to the actual values of angular velocity and angular acceleration, as well as time...

Thank you

Hi I am doing an assignment where I roll a tin can filled with car oil. This will affect its rolling because it distorts its centre of mass, resulting in an awkward rolling motion. I have already done the experiment, the first revolution is the slowest one by a lot because it slows down a lot...

The thing is that this is an experiment I have to perform. I have not been provided with any data but I can measure many things. I can measure mass, radius, velocities, pretty much anything I want. As for the problem, my teacher says that the point of this essay is to come of with a set of...

Homework Statement For my IB higher level physics extended essay I will have to calculate the angular momentum of a cylinder rolling down a slope. The cylinder is made out of copper and will be filled with a known mass of car engine oil. I think i can obtain the angular velocity fairly easily...
