Introduction: This experiment, Motion in One and Two Dimensions, repeats a famous experiment of Galileo, one of the first great physics experimenters, who lived in Italy more than 300 years ago. Instead of using the air table that is used in our version of the experiment, Galileo used the Leaning Tower of Pisa to drop objects and observe the free-fall of objects, which would be studied in detail. Galileo realized that a ball simply dropped vertically and a ball fired horizontally would hit the ground at the exact same time. In one dimension, the motion of an object movie with a constant acceleration a along the x-axis can be described by two equations: Velocity in the x-direction x-displacement Here x is the initial position, v is the initial velocity, and t is time. Similarly, for motion in the y-direction with acceleration a , we obtain Velocity in the y-direction y-displacement with y the initial position and v the initial velocity in the y-direction. In this experiment, the motion in one and two dimensions of a puck on an inclined plane will be studied.
