that is a very very good idea..does anyone else have any other tips?

Well, as practice, i calculated the Lspin of the Earth (Iw) and Lorbit of the Earth (r x p)..Now, the Lorbit>Lspin. So the question is, why can't the spin angular momentum be equivalent to the orbit angular momentum. The answer has something to do with gravitational forces or something

Why is it, in terms of gravitational forces (not relativistic terms), impossible that the Earth spin so fast that it have as much angular momentum in its spin as in its orbit? I'm stuck on this practice problem; I'm not even sure where to start. Any clues and important tips would really help...

This is merely a simple, but conceptual, problem. Say we have a cue ball of mass M and Radius R rolling without slipping on the pool table. What is the the meaning of the ∫v(t)dt - ∫Rw(t)dt where w(t) is the angular speed of the pool ball. My guess is that this represents the length the ball...

by looking at the equations of relativity, your answer actually does make sense; rotate or not, it will have the same final speed and thus same final mass! Thank you so much! Can anyone confirm this?

To a moderator: this is a theoretical, concept-based question. Say two balls of putty, moving relativistically near the speed of light, collide (although i understand this is not possible theoretically and realistically). They collide at a slight perpendicular displacement, instead of...
