Thread: Gravity Lighter on earth during.......

Ok get ready superguys n gals

I heard during a solar eclipse gravity is less on the ground for a few seconds because the sun and moon pull together as one.

meaning if you jump its 25% bigger

has this been documentented and or proven?

Maybe on the dark side of the planet. But you should weigh more if you are watching the eclipse.

I was about the only kid in my area that had a big welding lens and watched the whole eclipse. My teacher was afraid the rays of the sun were more powerful then the welding rays. Ha-ha. So she did not want others to look through them. I had brought more then one in.

Yeah you have that during every new moon phase, once in a month. Not only during solar eclipses. This constellation causes spring tides. But the effect on the actual weight is very small.

25%? Myth Busted! :-D

NASA would have scheduled its launches on eclipses. Saves the gas.

If it were really 25%, you'd be able to feel that difference without needing to jump.

Actually, to jump 25% higher, all other things being equal, means that gravity would be 80% of normal, which means that a normally 170 lbs. person would feel like they weighed 136 lbs. But that also means that on the other side of the planet, where the pull is downward, that person would feel like they weighed about 212 lbs. (though that wouldn't be exact as there are lots of details not accounted for). Either way, that amount is very noticeable. (My backpack, stuffed with books only weighs about 20 lbs, so imagine two very full backpacks worth of extra weight.)

Ouch!. No. Any change of weight would be due to tidal effect, or the differential of the gravitational effect of the Moon and Sun over the width of the Earth. As a result, you would weigh less than your normal weight on the opposite side, not more. This same effect is why there are two tidal bulges and not just one.

Hmm... That's a counterintuitive enough result that I'd have to do the math to see what's really going on.

I see your point,maybe i missed a decmal point lol 2.5%

I wasnt quoting facts but after more educated answers to the question

most say its true then to a small degree

thanks for your thoughts/input guys
