How friction helps us to walk and run?
please help me please fast

Answer 1

Answer: The force of friction is the necessary force which helps us to walk on ground. The friction is generated between the shoes and the road. We press the ground and as a reaction the ground pushes us forward. The force of friction between sole and ground provides the necessary grip which pushes us forward.

Answer 2

Answer: Friction helps us in walking as we push the ground backwards, we can slip if friction has not applied force forward , and thus the process goes on until we reach our destination...
