What good things can friction do?

Answer 1

1. It enables us to walk with out slipping.

2. The breakers and tiers of our cars and bicycles depend on friction to function properly.

3. The ridges in the skin of our fingers and palms enable us to grasp and hold objects due to friction.

4. To prevent patients being uncomfortable in bed rubber sheets with spongy under surfaces are placed over mattresses.

5. Nails and screws are held in wood by friction.

Answer 2

It allows us to move for one.

edit:

You can move in a frictionless world. Actually, a frictionless world would have several advantages over this world, most importantly, greatly increased mechanical efficiency. Friction doesn't make it harder to move, easier in fact. Instead, it makes it much more difficult to stop.

Answer 3

If we didn't have friction, then we wouldn't be able to stop anything moving, for example a car. Everything would keep moving.

Answer 4

helps in starting and stoping tho motion of an object. helps us to walk without slipping. helps us to apply breaks to our cars when driving.

Answer 5

it can make fire and if there was no friction braking systyms would not work

Answer 6

Our entire universe only exists because of friction. Without it, life, planets, stars, and molecules would never have formed.

Answer 7

tutti.
