When you pull a door open if the force the door exerts on you is equal to the force you exert on the door why dont you move?

-- The door's force on your hand is not necessarily equal to the force of your hand
on the door. If it were, then the sum of the forces at the hand-door interface would
be zero, and there would be no acceleration there to open the door. The point where
the action and reaction are equal is the point in your arm where the muscle is anchored
to the bone. Or better yet, between your feet and the floor.
-- You weigh more than the door weighs. So equal forces on you and on the door
produce more acceleration and more speed of the door than of you. (For the same
reason that the rifle recoils at a slower speed than the bullet's muzzle velocity.)
-- If you were on hinges, or on ice skates, then you would move too. The door's mounting
arrangement is built in such a way that it's more free to move than you are, when your
feet are planted and you're using your legs to keep you upright.

What is the space which exerts force on objects?
I dont know but i think something will crush youre brains and kill you
If two armwrestlers hand dont move the force must be what?
the force would be equal
What does force equal in science?
Your weight is a force. More specifically the force that keeps you from falling to the center of the Earth at this very moment! It is sometimes confused with mass because weight is often displayed in units of mass (i.e. the kilogram). Mass however does not change when you visit other planets, nor does it become zero in free fall as weight does. But, a force is not equal to weight because a force is a more general thing. In particular there are four fundamental forces in our Universe: gravity, electromagnetism and the strong and weak nuclear forces. Note that it is often the electromagnetic force that provides your weight; it is the electric repulsion between atoms that keeps you from falling into the floor!

How would you turn a bolt in space if there is no gravity to hold you down?
if you turn it one way, you turn the other way a small fraction of the amount it turned (the fraction being its mass over your mass). You dont need to be held down, as you can still exert force in low gravity areas..
