1 answer

One way to increase a ski jumper's potential energy is by raising the height of the ski jump hill. Potential energy is given by the equation \(PE = mgh\), where \(m\) is mass, \(g\) is the acceleration due to gravity, and \(h\) is the height above a reference point. Increasing the height \(h\) will increase the potential energy.
