The force of gravity is determined by your mass, the earth's mass, and the distance between the center of those two masses.

Your velocity does not affect the force of gravity. The fact that you may experiencing acceleration do to other forces, does not mean that the force of gravity has changed. The acceleration due to gravity is 32 feet per second per second. You would have to add a force that would cause the same acceleration in the same direction to cause the sensation of doubling the force of gravity. Keep in mind that force = mass x acceleration. So your mass would have to be known to calculate the force that would do this. When another force is applied at 45 degrees to perpendicular, exactly on half of the force would be added to gravity. The other half would be the horizontal component.

I don't remember the exact formulas, but there is a dusty thought in the back of my brain that the force of gravity is inversley proportional to the square of the distance. This would mean that you would have to dig down 3/4 of the way to the center of the earth to experience a doubling in gravity. Of course you could just apply weights, as that would be easier, and a whole lot cooler.
