Is VX and VY constant? Here are some formulas that describe projectile motion: Thus the vertical velocity (Vy) is continually increasing. The horizontal velocity (Vx) remains constant and is equal to Vxo. If an object is pointed at an angle, the motion is essentially the same except that there is now an initial vertical velocity […]
