Question

Why does pedaling up hill feels harder than walking up the same hill?

In: Physics

Answer 1

basically a bike and the way a bike works is adding more steps to your goal(which is to get up the hill) and so it requires more energy. That and the muscle groups required for you to go up a hill on a bike are different from the muscle groups required to go up a hill while walking. Also friction, on wheels, there is less friction preventing you from rolling down hill backwards, on foot your feet provide the necessary friction to prevent you from sliding backwards.
