Whoa hold on a second here. Why woul it be the "norm"? What would make it fall sideways?
Newton's first law of motions tats that every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line.
The predominate force acting on the buildings when they fell was gravity. What force would cause the buildings to fall to the side?
