Two bricks lie on the ground. One is laying flat on the ground and another is sitting straight up. Are both of these bricks exerting the same force upon the ground? If so how?
I know that the amount of pressure the bricks exert will differ, i understand that concept. I also know that the bricks force will be the same I just don't understand why/

Just as Pressure (P) = Force (F) / Area (A) gives you a smaller pressure for the brick sat on the larger area ..
The force exerted on the ground F = Pressure x Area ..
A smaller pressure, pressing over a larger area gives the same force as the larger pressure does pressing over a smaller area.
The force exerted on the ground F = Pressure x Area ..
A smaller pressure, pressing over a larger area gives the same force as the larger pressure does pressing over a smaller area.

The way the brick lies does not change its mass, nor the acceleration of gravity.
(M x G) = force.
The force is a figure NOT related to area of contact.
(M x G) = force.
The force is a figure NOT related to area of contact.

The force is the same, as you said ,it's just that they are spread over a different area.
