Imagine that there is no friction for a day .Make a list if things that it would not be possible for you do. Which things would still be possible

Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything. Imagine trying to climb a wall of ice without crampons and an ice pick. It would be impossible. From the human perspective, it would be impossible to stand up or even move. Simply crawling requires a force to make you move. That is provided by friction. With no friction, the only possible movement would be falling to a lower point under gravity.

Explanation:

1. We cannot walk .

2. We will not get a grip to hold things, then we cannot eat,write,Hold pen or pencil etc.

3. Moving things cannot be stopped.

4.Buildings cannot be constructed.

5. We cannot fix a nail to the wall.

6.We cannot stand properly without a grip.

7.we would keep slipping.

8.Nothing will be steady on ground. , things will not be at a proper places because of no grip.

9.Brakes in the car / vehicles will be useless.

10. Finally all the things, including us will be floating in the air.
