How Does Weight Loss Affect the Orbital Period of a Satellite?

AI Thread Summary
Weight loss in an isolated system, such as an artificial satellite, does not affect the satellite's orbital period. The mass of the satellite remains constant as long as the waste produced is retained within the system. Even if body weight is lost, the overall mass of the satellite does not change significantly, as the mass lost through exercise is negligible. The orbital period is primarily determined by the mass of the planet being orbited and the radius of the orbit, not the mass of the satellite itself. Therefore, individual weight loss has no impact on the satellite's orbital dynamics.

I weigh 200 pounds today on earth, now I go Into an Isolated System (Say, an artificial Satellite) for six months, I eat healthy foods, drink a lot of water and regularly exercize (due to lack of anything else to do :D), so I'll lose weight, and hence mass.

1) Will there be any change in the time period of the satellite?

2) If not, which means the satellite has the same mass as when it was launched, where is the mass that I lost by exercizing?

Well, if your waste isn't thrown out of the space station, but kept on, the overall mass of the station will never change as long as you stay on...
 
Over 100 days your body will have radiated away the equivalent of roughly 10 mcg of mass. :)

and even if you did toss the waste (or the lost body weight), the mass of the satellite has (virtually) nothing to do with the orbital period. it's the mass of the planet the satellite is going around (as well as the radius of orbit, assuming a circular orbit) that controls the period.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
