    Gravitational Force/Earth Rotation Question

    Well yes, there are always forces from other sources in play, but when you add a force exactly opposite to the force of Earth's gravity, then the only forces acting on it will be the forces making it orbit the sun, the galactic center, etc., without the force of gravity from the Earth that keeps...

    Gravitational Force/Earth Rotation Question

    Ah, so the coriolis effect is caused, in some ways/situations, by having the centripetal force of gravity overcome? With my example of applying the upward force, I mean that the apparent acceleration of the object is slightly less than its true acceleration (some if its acceleration is what...

    Gravitational Force/Earth Rotation Question

    I suppose my question is more about this: would a rocket launched vertically upward find itself to no longer be above the same point that it launched from as it kept moving upward? Also, making something "float" requires that you cancel out its weight, but not its centripetal force of gravity...

    Gravitational Force/Earth Rotation Question

    I'm wrong, centrifugal force does not exist, however the centripetal force needed to keep us rotating with Earth does exist and can be overcome. That's my question, wouldn't anything that overcomes the force of gravity (both weight and the centripetal force component) appear to slowly...

    Gravitational Force/Earth Rotation Question

    Ah! I think I see now. The only force that gives us weight is the component of the force of gravity (almost the entirety of this force) that is left over after the force of gravity overcomes the centrifugal "force," and no upward force on any body on the Earth can make the force of gravity stop...

    Gravitational Force/Earth Rotation Question

    Does the force have to be exactly equal? Or would any force that is greater than gravity also have the same effect? I would think that any force overcoming gravity would make an object stop rotating with the planet. Conservation of momentum is only true without an outside force on the system...

    Gravitational Force/Earth Rotation Question

    The force of gravity is what makes things on the Earth rotate with it, instead of flying off. Doesn't this mean, however, that if you were to apply an upward force on something exactly equal in magnitude to the gravitational force on the object (so the net force on it is 0), it would cease to...
