In this lab you will perform experiments to understand and analyze the motion of a projectile. A projectile is any object that is given an initial velocity. Once it is moving through the air, its path is dictated by its initial velocity, and gravity. Interestingly, the horizontal and vertical components of the motion are mostly independent. The gravitational acceleration is acting in the vertical direction only; and there is no acceleration in the horizontal direction (if air resistance is small enough to be ignored). Refer to the text on chapter that involves Kinematics in Two Dimensions and Projectile Motion. Your textbook contains a section on the theory of projectiles, and we have discussed it in class. The following summary is here to remind you of some key parts that might be useful.
