It's a naive question, but I'm pretty sure my professor said that space-time is locally flat (and I'm pretty sure that the volume of my room counts as "locally").
That said, I would expect falling objects to follow straight trajectories, but that's obviously not the general case.
I thought...
Hey there!
It seems to me that your definition of unique is lacking something.
why would 6 be unique? 2*3 and 1*6 are two ways to generate it.
if "unique" means "there is only one combination of numbers that multiplied generate this number" then you'd be looking for prime numbers (every...
I tried with Lagrangian and Euler-Lagrange equation but I really don't know where to start writing kinetic and potential energies in cartesian or spherical coordinates.
I tried with a coordinate system that moves together with the disc (longitudinal and vertical axis, as it is usually done when...
Homework Statement
The system is made of a disc the center of which is pinned to the origin (so the disc cannot translate), and some weights that can be stuck on the disc to make it tilt (weights do not translate on the disc) (see images attached).
There is no friction whatsoever. The only...
ok maaaaybe I should have posted this in the homework section, if no admin moves the thread by tomorrow I'll just repost there :D
i'm deeply sorry for the trouble.
The system is made of a disc the center of which is pinned to the origin (so the disc cannot translate), and some weights that can be stuck on the disc to make it tilt (weights do not translate on the disc) (see images attached).
There is no friction whatsoever. The only force is gravitational...
