Do mountain climbers eliminate friction to overcome gravity to keep from falling?

Answer 1

Nope - they use friction to stop themselves from falling ! The various pegs, clamps etc rely on friction to hold them in place.

Answer 2

Mountain climbers use a combination of techniques and equipment to manage friction and overcome gravity while climbing. They rely on proper technique, using their hands and feet to maintain contact with the rock surface, as well as specialized equipment like ropes, harnesses, and anchors to provide security and support in challenging terrain. Eliminating friction entirely would be difficult and dangerous, so climbers focus on minimizing it through proper technique and using equipment effectively.
