(ELI5)why is a person easily tired when walking on rough surface?


I find myself difficultly tired when I walk on smooth surface but on rough surface, I am easily tired. Is it because of friction force?

In: 1

On rough surface your body muscles are doing a lot more work balancing your weight that’s why you become slower and it becomes somewhat a bit more tiresome to walk.

If you mean rough like carpet versus smooth like tile…. Pick up your feet.

Otherwise a flat surface uses less muscles, sloped will engage more muscles. Rocky, snow, and such terrain would involve more or less muscles depending on the terrain.
