eli5 – Why are switchbacks more efficient when hiking?
In: Physics
It’s a basic machine (ramp) that eases the force needed to go up a hill. They allow you to go the same vertical distance over twice (or whatever) the horizontal distance. So, while it may take longer it’s less strenuous.
Also, from an erosion standpoint they keep water from shooting straight down an incline where it would erode the trail really fast.
