False. Air itself will exert no force, gravity would be exerting a force on your head and as a consequence it would be the force of gravity acting on you and as gravity has a constant downwards force of 9.81m/s this would be the force acting on you.
Short answer, no air doesn't execute such an extreme force on your fragile head.

buoyancy is the upward force that water exerts on an object. :)
Yes, anything on the surface of the planet which is at rest exerts a force on the ground and the ground exerts a force on it.
it moves

False,since it's an air resistance and it's a contact force.
False. Every object attracts every other object, through the gravitational force.
True, blood pressure is the force that the blood exerts against the walls of the blood vessels, usually the arteries.
true
Gravitational force exerts an attraction on objects.

The net force on the ball is not zero. The ball exerts a force on the wall (the action), and the wall exerts an equal and opposite reaction force on the ball. These two forces do not sum to zero as they are acting on different objects; the action of the ball acts on the wall and the reaction of the wall acts on the ball.

It exerts normal force to you.
