The object is thrown horizontally at a certain initial velocity. If the object is only subjected to gravity, such motion is called a flat throwing motion. The flat throw motion can be regarded as a uniform linear motion in the horizontal direction and a combined motion of the free fall motion in the vertical direction. The object of the flat throwing motion is a constant force due to the external force received, so the flat throwing motion is a uniform shifting curve motion, and the moving trajectory of the flat throwing object is a parabola. The flat throw motion is the curve motion The time of the flat throw motion is only related to the vertical height of the throw point; the horizontal displacement of the object landing is related to the time (vertical height) and the horizontal initial velocity.
