I know that there has already been a thread on the physics of waterskiing, but I don't think most people know what wakeboarding is. I am doing a research project on the physics of wakeboarding and am having some trouble grasping some of the key concepts. For those of you who don't know, wakeboarding is just like waterskiiing, but with a board rather than two skis. You hold the rope just like in waterskiing, but your body is facing perpendicular to the direction the boat is moving. I am under the impression that buoyancy has very little to do with both standing up on the board and with remaining on top of the water. A wakeboard is a curved board on both sides so the main principles I believe are acting on the board are the horizontal force of the water being translated into vertical force by the angle of the board and tension/force of the rope acting on the boarder. The main problem I am having is how a wakeboarder actually pops off the wake. In all the training videos/websites etc., they tell you to progressively edge towards the wake to keep the tension in the rope very, very tight. About 2-3 feet before you hit the wake, slowly start to stand up and the tension in the rope combined with the motion upwards will create a pop off the wake. I do not understand how this happens. Any help would be greatly appreciated.
