The Physics of Wakeboarding

Ever since I was a young child, the sport of wakeboarding has fascinated me. I first learned how to wakeboard when I was eleven years old and have been hooked ever since. If you are unfamiliar with the concept, wakeboarding entails being strapped into a board and then having a boat or other watercraft pull the rider while they hold on to a tow rope, with the goal of using the wake of the boat to boost the rider and the board into the air to do tricks.

When analyzing the physics behind wakeboarding, first you have to look at how the rider initially stands up out of the water. This is made possible by the boat starting to move forward, which creates tension in the tow rope that the rider is holding. Once the boat moves far enough that the tension can counteract the riders force of gravity, then the rider can stand up on the surface of the water while not breaking the water tension. As long as the tension equals the weight of the rider and resists the friction that is present on the rider, then the rider will move at a constant speed. In order to move faster, the rider will have to either increase the tension on the rope by leaning back on the board or the boat will have to increase its speed which increases the tension on the rope. In order to be able to jump the wake, the rider first has to lower their center of gravity by leaning backwards (I previously stated that this increases the speed of the rider), which creates more tension in the rope, while bending their knees and then slowly standing up as they approach the wake. When the rider then hits the wake, the rope will pull them up and raise their center of gravity into the air.
