Velocity Analysis
After the players were recorded, the video was put into the Logger Pro software to be analyzed for velocity of the swing. The videos were scaled to the size of a regulation racquet (0.68 meters), and the tool to make points in video analysis was used to determine slope and therefore velocity of the swing. Through plotting of the point, position-time graphs were created, and the slope of the x axis and y axis were found. Pythagorean theorem was then used to determine overall velocity.
Below are all data combined. How the data was collected can be seen below. Velocity was determined assuming no air resistance and using projectile motion. Aerodynamics of this will be discussed in the later page, "Physics Behind Everything".
