No simply an invention. There are no moving parts (other than locking the boots into the skiis) or complicated pieces that move automatically once some work is inatiated. They take advantage of phycis in that they reduce the friciton between you and the snow. The time it takes to get down a hill can also be calculated given distance, angle, acceleration...
Water skis can be classified as a type of lever, which is one of the six classical simple machines. When a skier is pulled by a boat, the skis act as levers that allow the skier to lift and glide over the water's surface with minimal resistance. This leverage helps distribute the skier's weight, making it easier to balance and maneuver while skiing.
