Question

Is walking desirable or undesirable in friction?

Answer 1

Answer:

walking is a case in which friction is desirable.

Explanation:

This is because if we try to walk on a surface in which friction is less (or none), there is a high chance that we might fall. Besides if friction is absent, we will not be able to stop, turn or perform any other activities which require us to change the direction of force.

Here Newton's First Law is applied which states that an object will continue to remain at rest and a moving object will continue to move unless an external unbalanced force acts upon it.

Friction is the unbalanced force.

Answer 2

Answer:

Walking is desirable in friction because the less is the friction more smooth the surface becomes and so we can’t walk.

Friction is essential for walking
