Is there any software, free or commercial, which students can use
to perform physics lab experiments online?
I'm looking for a software for college physics, say, from Linear motion, motion under gravity, Newton's laws, Energy, momentum, Rotational dynamics, to Heat and Thermodynamics.
CD or...
Too much censorship in these forums.
Not only in social threads, censorship runs into scientific threads as well.
I refuse to type anything when I can't express my thoughts.
Sorry, I was talking about Physics Forum site.
You all are saying there is no way to totally remove my profile or account from this site, once I sign up for this site?
Doesn't it violate some kind of law, specially laws of ethics?
I tried once before but couldn't delete my profile or membership.
I'm not learning anything new from the sight,
and no one is learning anything from me either.
I see no reason to keep my profile/membership on this site.
Please let me know how can I delete my membership on this site.
One purpose of colleges/univs is to make students Jack of all Trades, Master of none. They become masters of something when they go to work. Those who are capable of becoming masters at Univs do not need too much of teacher's help.
My comment about 100-200 pages was a bit of exaggeration, but I...
There are generally 3 groups of students in a class, interested, semi-interested, not interested. I understand the 3rd group is in the class because it makes college/university look good by raising size of enrollment.
My suggestion, teach only the first 2 groups. Self-tutoring is totally...

I also got a very similar equation, a quadratic equation, but my equation
included not only g, R, and V (ω) but also μs, coeff of static friction between m and M.
Is μs embedded in one of your constants?
If the hoop doesn't have linear velocity, the angle will be the same as m falling from an inclined plane, related only to μs, coeff of static friction between m and M. If the hoop gets a velocity, the result is a quadratic equation in Cos or Sin of the angle. Quite solvable.
Look around you, do you see anything "infinite"? A guppy in the middle of Atlantic will conclude after all measurements Atlantic is infinite.
A curvature can have many "centers of curvature" when it is divided into sections. Saying a geometrical shape has no center is "practically incorrect".
Bander and root:
The center is located off the surface.
Any shape has a area, on or off the shape, we can identify as center. Otherwise, the term 'center of curvature' is meaningless.
The universe has no center.
OP was not asking for a center of a circle or center of a sphere.
Any spatial region must have a central 'region'. The region may
shift or constantly shift, but there must be region that we can call
central region of the universe.
Just because it is beyond the...
QM objects do not have properties until measured?
Another way of saying this is
To a quantum particle nothing exists until it interacts with another 'object'.
From the 'object' point of view: a quantum particle doesn't exist until it interacts with the 'object'.
Collisions (scattering) with around 25000 electrons, which is not too high compared to the path the photon will travel, will increase its wavelength from 510 nm to 570nm by Compton Scattering.
FBI couldn't stop the shooter before terrorist attacks with their billion dollar budget, what are the chances they would stop
future terrorist attacks using phones? No one should buy FBI arguments.
