Any good anagrams for theory of projectiles?

Is the investigation of the path, or trajectory as it is called, of a body which is projected into space. A body thus projected is acted upon by two forces, the force of projection, which, if acting alone, would carry the body onwards forever in the same direction and at the same rate; and the force of gravity, which tends to draw the body downwards towards the earth. The force of projection acts only at the commencement of the body’s motion; the force of gravity, on the contrary, continues to act effectively during the whole time of the body’s motion, drawing it farther and farther from its original direction, and causing it to describe a curved path, which, if the body moved in a vacuum, would be accurately a parabola.
