My Gravity Theory

Hmmm I didn't realize she called Pluto a planet

You're right, she didn't. I was just being random.

ha ha...you came to the right place. Being a PhD in physics I couldn't help but solve this one (although you don't need anything more than highschool physics for this one!)

Ok, sad I know,l but here goes:

firstly we use Newtons Gravitation formula:

F=GMm/r^2

Where G is the Gravitational constant =6.67E-11
M = mass of the Earth = 5.974E24 Kg
m= mass of thing you are lifting ... I used 100 lbs which is 45Kg
r is the distance from the Earths center. I used a radius 6378km for ground level, then recalculated adding 10m which is about 30 ft as the gentleman specified.

comparing the two answers using

% diff = (ans 1-ans2)/ans1 * 100

Gave a percentage difference in the weight to be 0.0003%.

thus, your 100lb weight would in fact be one thirty millionths of pound lighter, and thus the effect is only in your imagination...unless you have studied zen and have hyper-elevated perception.




....hmmmm....we could also do a coriolis force calculation just in case the gym was also at a different latitude....

That was one of the most bad ass posts I've ever seen. Thanks!

my body is sensitive enough to feel a one thirty millionth difference in load.

Not that load you fag.

This will have no real world application in the weight room, of course. Rusting will cause more of an effect than gravity.

This is true. Rust will probably have a million times more of an impact than which floor your weight room is on.

This is true. Rust will probably have a million times more of an impact than which floor your weight room is on.

So will the air circulation in the room and the density of the air on that day. it won't effect the actual weight but it could add more friction as you move the weight through it's range of motion.

Time isn't slower with distance from the Earth... it is slower as you accelerate but even then it is only slower relative to an observer on Earth

Its slower as you get closer to any gravitational source, and theoretically goes to zero inside a black hole(to an external observer). You are right about the acceleration, but Einsteins principle of equivalence states that an accelerating frame is indistinguishable from stationary frame in the presence of a gravitational field.

Maybe one place uses 55 pound bars and you didn't notice?

Pfft. We are trying to provide real answers. You can't be bringing a ridiculous explanation like that into this discussion.

Thats what I originally thought, but the "trainers" seem to think they are 45 pound standard Olympic barbells.
