The sucker is dish shaped, when pressed against a smooth surface the air is forced from beneath the sucker.The rubber makes an air tight seal and the air pressure outside is greater than the air pressure beneath the sucker, thus forcing the rubber sucker to 'stick'.

∙ 6y agoNo. A rubber sucker requires an air-tight seal. Atmospheric pressure pushed on the rubber to prevent it being pulled off. It is not possible to get an air-tight seal on a rough surface.

∙ 13y agoA rubber sucker works by creating a seal between the surface and the sucker, it hold because in order to remove it one has to temporarily create a vacuum and this requires a lot of energy. On a rough surface an airtight seal cannot be made as air can escape under the sucker, and so no such vacuum can be formed and the sucker does not stick.

Sucker pressed on smooth wall sticks to it due to air pressure . It sticks to wall since the pressure outside the wall is greater than the pressure

Why do suction cup stick to wet surfaces better than dry surfaces?
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.

Friction is caused by how many surfaces rubbing together?
Friction that is caused by the movement of two surfaces against each other is known as kinetic friction. This is different than static friction which is opposition to motion before the motion occurs.
What is the physics behind an arch?
Picture the arch. It resists the pull of gravity. The force of gravity is a constant, and it wants to pull the center of the span down. But the materials distribute some of the force sideways. The sides of the arch support much of the weight of the structure, but they have to be designed to resist being "pushed apart" by the arch as well as to hold it up. Take two sticks and a smooth table top. Stand the sticks a little apart and tip them to where the tops touch. Put just a bit of tape there to keep the sticks touching and pushing on each other. With a smooth table and a goodly space between the bottoms of the sticks, the sticks will slip sideways and fail to stand up. That's the "down" force of gravity acting along the stick. It pushes down, and the sticks resist. And some of the force is vectored "along" the stick and causes an "outward" push. It's an experiment that shows the "down and outward" force on the sticks, and the arch experiences similar forces. There are some other considerations that must be looked at in arch construction, but those two are the primary ones. It is the "down" and the "out" forces that are greatest in the arch. Links are provided to relevant Wikipedia posts. One is to a nice drawing, and the second is to the article on the arch. If pictures are worth a thousand words, there is a book here. And there are arches that have been standing for a thousand years, too!

Right, first things first, every one thinks you hit with the rubber end, BUT YOU DONT! You hit with the other end, you hold the rubber end. You just play them as normal sticks aswell :).
