There is only a difference in gravitational force of about 1 ounce (or less) per hundred pounds between the poles and the equator. Gravitational force is weak. You can calculate the difference using trig. This in the face of a pear shaped planet earth.

Ill teach you about gravity.
Get in a swing go up and down till you can go as high as you can go with out the chain going slack then jump off at the highest point. Then see what happens.
Omg its magic harry. Gravity has been solved.

I think you're getting confused between gravity and centrifugal force. The centrifugal force is minimal in your examples, because the diameters in question are so large.

Eg. the Earth may be spinning at 1000mph at the equator, but we are so far from the axis that the centrifugal force is negligible. Same with the solar system spinning round the galactic centre.

That's why we don't fly off the Earth at the equator, or get squashed at the poles.

(anyway, we would never actually get squashed at the poles, even if the Earth was spinning fast enough to make us fly off at the equator, because a lack of centrifugal force does not magically increase the gravitational force of an object. The gravity is due to the mass of an object, nothing to do with its rotational speed.)
I thought you would say is, are you not so sure anymore?
Centrifugal force negligible the further way you go from the axis?
Take a rock on a string and turn it so that it takes the same time for one rotation with different lengths of the string.
Some laugh (centrifugal force at work)

Come on, folks. Everyone knows flat earth is for people with flat feet. Or did their flat feet make it this way?
Round earth theory and evolution theory don't match. Those religious crackpots were right after all! Roll Eyes

  • The Moon does not fall into the Earth.
  • The Earth does not fall into the Sun.
  • Satellites do not fall into the Earth.
Yes, it does.
Yes, it does.
Yes, they do.


It's like watching sediment swirl around the drain before being sucked in...

but on a larger scale.

In a few weeks, maybe, the moon will fall into the Earth.  A couple months until we hit the Sun. 

PANIC SELL!

Wait, is the earth flat or not?  Cheesy

Of course it's not flat. It's geoid. That wasn't funny.

    • Why is gravity so strong to hold people, buildings and the oceans stuck to a spinning ball-Earth, but weak enough to allow balloons, birds, bugs, flowers, and smoke to easily rise against its awesome force?
    [/list]

    You're not a physicist are you? Most of these don't even warrant a response but smoke and the gas in balloons are lighter than air so they float. And if birds didn't flap they'd soon meet the fate of gravity.

    Nope they meet the faith of density like everything else. To make things easy for you. Gravity is simply density and buoyancy.
    You are more than welcome to quote every single point.

    Gentle lift of and gravity.

      Back of Turtle is all I know about how gravity works.
      If the turtle is not carrying the heavy shell unfortunately density keeps the hard heavy shell at bottom and weaker belly with stumpy legs up.

      More about gravity:
      • With the rotation speed of the Earth (in ball terms) being much faster at the equator than further north or south, surely this affects the magical force of gravity?
        So, if I'm standing on the equator at the widest point of the alleged globe, spinning at 1000 mph, my weight will be 175lbs, if I then fly to either north or South poles (not actually allowed but lets wave that for now) at the narrowest point of the alleged Globe,the rotation of the earth would be reduced to around 150 mph, The gravitational pull if existent would have to be so great that my weight would be around 7000lbs and I would be squashed like a bug.
      • The Solar System is travelling at an average speed of 828,000 km/h or 514,000 mph within its trajectory around the galactic centre but this somehow has no affect on the magical force of gravity either.
      • The Moon does not fall into the Earth.
      • The Earth does not fall into the Sun.
      • Satellites do not fall into the Earth.
      • Gravity is so strong that upside-down water at the surface of the ocean (near air) is being pulled to the centre of the earth but this force is also not that strong, in that this water can move in any direction with currents and tides, and be easily scooped, splashed, and thrown by a human hand.
