Why skis do not sink into the snow |
|
Answer» I hope it's help you ( ◜‿◝ )♡Explanation:Skis create a large CONTACT AREA between the skier and the SNOW. Therefore, the weight of the skier—or how much GRAVITY pulls on him—is spread out over a larger area. The skier presses less on each square INCH of snow, and instead of sinking into it he or she can glide over it. |
