If a person who weights 450 lbs were to freefall, does that mean that they would be going 450 mph? I know I learned this in high school but I forgot..

If weight is the measure of the gravitational pull on something, then why wouldn't a heavier object with the same surface area(wind resistance) as a lighter object fall faster. Wouldn't its greater gravitational pull make it fall faster toward the Earth. Does it actually fall faster, but it is nearly incalculable because of its size in comparison to the mass of the Earth?

Remember the tube is a vacuum and the conditions include zero-gravity.

I guess my real question is will the object remain suspended in exactly the same location within the tube or will it stop in the same location regardless of the moving tube and end up colliding with the walls of this glass tube?

I saw a TV program where Americans were trying to make a danger sign that civizations in the future (after the collapse of our own) would understand after nuclear waste was to be buried in an underground salt mine. Did they make one. If so what was it.

Math wise Energy level structure of atoms can be described as discrete mass level as well. If that is the case than the electron mass radiates energy in terms of mass,Isnt that true?
So why did he state that the electron mass as a constant?
Isnt that why his model failed with more complicated atomic structures?
