Where Can I Buy A Pair Of Gravity Boots?

[Doc Tinker]

The other day, I read in the paper that scientists have determined that the earth's rotation is slowing down. They say that we slowed down by about 1/1000th of a second during the year 2001. When do I need to start worrying about finding some gravity shoes, so I won't drift off into space?

Well just eat more chicken fried steak and taters

Walmart will have the boots when the time is right.

Welcome back Doc. We missed you.

Hey Doc is back and we have some extra entertainment again. Welcome back Doc.

I've always wondered where people get the idea that the rotation of the earth has everything to do with gravity.



The earth's mass is responsible for our gravity.



The mass of the sun and moon affect our gravity also and they are a long way from our earth.



A question: what is the rotational speed of the moon?

======================================

Definition of gravity



Physics.

The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body.



The natural force of attraction between any two massive bodies, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Good point Jumbo Jet. Doc, maybe you'd better go back on vacation.



I suppose we make the connection between earth's rotation and gravity because of Sci movies where a rotating space station simulates gravity. Note that the word is simulate, not create. I was a little suprised to hear the the new international space station does not use this technique. They said it would be too complicated with today's technology. I like the sceen in 2001 Space Odessy (sp) where the guy is running laps around the perimiter of the space station.

Thanks for the gravitational lesson, Jumbo Jet. We'll all gravitate toward your classroom for some more gravitating learning, where you will see our gravitude on our faces. LOL



Looks like I'll have to restart this thread asking where to find a giant sunlamp, incase I live on the dark side when the earth stops rotating.

The way I see it is, all the heavy hitter BOMBed Diesels are east of the Mississippi.



We tend to drive one way faster than the other, for what ever reason.



If we could get some power on the west coast, we may even the Earth back out.

The moon doesn't turn. it just revolves around earth. That's why we never get to see the other side except at new moon, when you scn't see it.

Here's a shot of the backside... #ad

The phase of the moon, new/full is only the shadow of the earth on the moon. The backside of the moon never faces earth since the moon doesn't rotate. The only times the backside of the moon has ever been seen was by the Apollo astronauts when they orbited it and by high jumping cows.

What if everyone pointed our trucks the same direction (I'm not going to try to figure out which way, Jumbo Jet can do that) at the same time and did a full power burn-out. Do you think we could get her back up to speed again.

We'll undo our effort when we step on the brakes. Wait! we could turn around 180 before stepping on the brakes.



OK, let's sincronize our watches

 

[klenger]

Or coast to a stop.

I'm afraid it's too late.

I believe you are incorrect. When the earths shadow is on the moon, we have an eclipse. You are correct that the moon dos not rotate, but it revolves around the earth and different sides are presented to us. We can not see one side because it is not illuminated by the sun.

The moon does rotate. The period of rotation is the same as the period of the moon around the earth (like a tether ball around the pole). We only see one surface from earth.



Actually, if the earth is slowing down we would feel heavier because of the lack of offsetting centrifugal force. That is why Cape Kennedy is located where it is (better weather, too). It would require more fuel to get to outer space as you go further north. Maximum weight at the north pole. Best fuel economy would be on a high mountain at the equator.

I like Papa's response. It expains why I weigh more today than I did a year ago.
