The motion in the horizontal direction seems to be at a constant velocity (had air resistance not been involved). Background Information: Projectile motion is a form of movement in which the projectile or object is thrown near the earth's surface, moving in a curved path because of the influence of gravity (9.81ms ), whose direction is vertically -2 downward, causing that the object experiences the same acceleration as it does in free fall. Set up the launcher to launch at an angle. In EXPERIMENT 1: Projectile Motion. We will also predict the range of a projectile. Projectile motion occurs when an object in a two dimensional plane experiences motion only due to gravity.
