In order to create artificial gravity you would need to have the space station constantly accelerating in one direction so that the people inside would experience a force equal to the rate of acceleration times their body mass. This would create the illusion of weight. This is impractical...
I have been working on making a 2-dimensional physics simulation on my computer and am having a bit of trouble with collisions. I know that:
-horizontal momentum is conserved
-vertical momentum is conserved
-kinetic energy (both rotation and translational) is conserved (assuming elastic...
I was looking at the moment of inertia list that they have on Wikipedia and noticed that the moment of inertia for a regular polygon was rather complicated. I did the calculation myself and found a significantly simpler result of
I = (m/6)(3+tan(pi/n)^2)*R^2:
m is the mass of the...
What would you do if you wanted to find the angular momentum of the Earth around the sun? Would you need to consider both the rate at which the Earth orbits the sun and the rate at which the Earth spins around its own axis?
Suppose I am floating in space and have a thin rod oriented vertically floating in front of me. This rod has its center of mass in the center of the rod (uniform mass distribution) and is not fixed to anything. I then throw a point particle with non-negligible mass horizontally;it hits the rod...
