What causes grass skis to slide over the grass?

Answer 1

Grass skis slide over grass primarily due to their smooth, flat bases, which reduce friction between the skis and the grass surface. The design often incorporates materials like plastic or a similar composite that enable easier gliding. Additionally, the weight distribution of the skier helps minimize resistance, allowing for smoother movement across the grass. Finally, the angle of the skis and the speed at which the skier moves can further enhance the sliding effect.
