smooth surface.
You will need a very smooth surface that has less friction.
The surface of electric machine are smooth why
on a smooth surface
Smooth surface
seeing as comets are just bits of huge rock. Comets can be smooth, jagged, bumy, or a combination of all 3
While a horses teeth are fairly long the surface is relatively smooth as a general rule. However a horses teeth can become jagged from uneven wear from chewing.
because if they have a smooth surface they ski faster
Weathering and erosion. Weathering causes rock to break into smaller particles. When these particles are transported by wind, water, or ice, the jagged edges from fracture are gradually worn down from abrasion with other particles, making the outer surface appear relatively smooth. Sometimes the mere abrasive effects of windblown particles on a rock will smooth the exposed surface, leaving the remainder of the rock jagged.
Less friction
Mountains are jagged because that is how they are formed. As they get older, erosion will begin to smooth them out so they appear rounder.
Wind and water erosion makes the mountains smooth.
Erosion after millions of years have caused the jagged edges to smooth out. Hi

the smoother the surface the faster you go the bumper the surface the slower you go. smooth surface less effort to go farther and vice - versa
