Physics Question?

Question

If my eyes see everthing upsidedown
and my brain turns it all rightsideup
what keeps me from falling off the earth?

Answer 1

Simple--the earth sucks.

Answer 2

your mass

the attractive forces between you and the earth go as the following

Force of attraction = G x mass 1 x mass 2 / r^2

g is a universal gravitational constant
mass 1 is your mass
mass 2 is the mass of the earth
r is the distance between your center of mass and the earths.

if mass 1 = 0, force would be zero and you would float off into nowhere.

of course, the earth's mass, your distance from the earth, and the force associated with gravity are all correct answers as well.

Answer 3

The first and second parts of the question have nothing to do with each other.
The earth's gravity will act on your body independently of how your eyes or your brain work.

Answer 4

They are all absolutely right.
Here's a philosophical question for you though - how can we prove that what we all see isn't upside down. you might see things the other way up to the rest of us. if you don't think so, i bet you can't prove it.

Answer 5

gravity always tugs in the same direction, despite what your eyes and brain are doing.

Answer 6
