Explain why you either agree or disagree with this statement. In this activity you will use the equations for motion in a straight line with constant acceleration, and the projectile model to solve problems involving the motion of projectiles. The objects motion generally stops after a particular time, so the time is the same for the xdirection motion and the ydirection motion. Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. These are three types of the most common problems questions of projectile motion.
