Question

How does friction help us in walking?​

Answer 1

Answer:

So, a normal reaction by the foot on to the ground gives rise to frictional force, which pushes us forward. Complete step by step solution: ... The horizontal frictional force acting towards the right, which acts opposite to the effective horizontal force applied by our foot prevents us from slipping while walking.

Answer 2

Answer:

Frictional force helps us from slipping while walking. Normal reaction by the foot on to the ground gives rise to frictional force, which pushes us forward.
