Question

we can't walk or run without what​

Answer 1

we cannot walk or run without leg

Answer 2

We can't walk or run without the force of friction.

- We can walk or run only due to the presence of force of friction.

- When we apply force with our feet in the backward direction, then a frictional force comes into play in the forward direction.

- Due to this forward frictional force, we move forward.

- In the absence of friction, we will not be able to walk or run.
