I had a little thought experiment, in which there are two objects with the same masses near each other (same height) on freefall. If I set up a point that is on an instant besides the two masses and call it the center of torque, I get that the torque produced by the nearest one's weight is T=F.d, where d is the distance to the imaginary point. The other one is T'=Fd', where d'>d and F=mg. I find that the torque T'>T and so I expect a'>a, where a is angular acceleration. But for a small instant of time, the geometry of the problem will tell you that the angle of the first mass made with the point (call it o) is larger than the angle the other one is making, because they are falling on the same rate. And so o'<o and a'>a. That for me is very difficult to understand why... Am I missing something? Thanks in advance!
