In what you linked, the result have L/m; L/m made m disapear. Im right?

I do not understand why the mass is important. I think that if any planet, no matter its mass, is at any point at any velocity, the orbit is just defined. I´m wrong?

OK. I understand now why. At the same distance, the aceleration is the same, but not necesary the velocity, so the orbits are not the same. And being different the velocities, the sweeped areas are not the same! Thanks!

I mean. For example, Earth in one month sweep the same area* than Jupiter in one month? *The line joining the Earth with the Sun than the line joining Jupiter with the Sun. I think yes, but is not what 2nd law says. I think in the fact that the aceleration just depends on the distance to the...

Thanks guys!

Thanks guys!

Sorry Vanadium but yes, the answer was too complicated for me. May be Phinds tought I will could handle this answer. Well, shamely for me, is not the case. I could just said : Thanks Phinds! As I understand his answer... well, I´m not a lier. I still hope someone could help me with an easier...

OK... thanks Phinds! But... I found in lot of places that use of the uncetainty principle related to time a virtual particle could live. What i do not understand is why a >= turns into <= I have not the necesary math to understand it seriously. I just want for any kind of easy explanation. Sorry.

Hi! I could understand gravitational force as a force that move mass. I could understand electromagnetic force as a force that moves chaerged particles. I even could understand strong force as a force that atrack protons I could not understand the moment of what weak force changes. The moment...

Hi people. Having as uncertainty principle that ΔE Δt≥ h/4Pi, why Δt≤ h/4PiΔE to allow the existence of a virtual particle? How ≥ becomes ≤ ? I think... real particles must obey ≥ so any particle that do not obey that is a virtual particle and thus why virtual particle needs to obey Δt≤...
