Freefall Freefall Why does a baseball that is thrown follow a parabolic path? This question is central to the study of projectile motion. Galileo was one of the first to study projectile motion. He correctly deduced that part of the motion of a projectile (such as the baseball) was accelerated and part of its motion was uniform. Suppose that a bullet is loaded into the barrel of a gun. Another identical bullet is held at the same height as the bullet in the barrel of the gun. At the moment that the bullet is fired from the gun, the held bullet is dropped. Which hits the ground first? The correct answer? They both hit the ground at the same time! According to Newton's first law of motion (the law of inertia), the bullet fired from the gun will continue in motion at the same speed unless acted upon by an outside force. The horizontal motion of the fired bullet is constant. The downward motion of both bullets is the same as a body in free-fall. Vertically, both bullets are uniformly accelerated by gravity. Both bullets are identical and are dropped from the same height.
