cted through the air do not have a con-stant downward acceleration, because of the resistance which theair offers to their motion, and therefore the simple theory of pro-jectiles above outlined is not applicable in practice. The limita-tions of this simple theory may be stated in a general way… … ~a¥L.~ of mass of the body describes in every case a smooth paraboliccurve in accordance with the discussion of Art. 36, air frictionbeing ignored. Thus, if an iron bar is thrown through the air, thecenter of mass of the bar describes a smooth parabolic orbit; or ifthe bar is projected by hitting…
