But that law can’t be right, because I can violate that law very easily. A ball should be on the floor, because it is more dense than air. But I can throw it up into the sky, and it is then moving upward in violation of the law.
Is there some corollary that is added to this law to account for such cases?
Thrust just like a airplane motor and wing design.
With out thrust an air plane isn't moving.
With the ball once your thrust runs out it over.
No matter how hard you through your ball its coming back to the floor.
Okay. What is thrust, exactly?
You see, I have two magnets. And I can suspend one of the magnets above the other, and it just stays there. I put guard rails on each side so that bumping the table doesn’t knock it off alignment. It has been this way for several years, in fact.
Is this also thrust? If so, what is “thrusting?” And will the thrust ever run out, or is this an exception to the law of density and the law of thrust?
