Suction cup holds onto to surfaces | Atmospheric Pressure | Physics

The principle behind suction cups is explained in this video. Suction is a phenomenon that happens because of atmospheric pressure. If a little air is removed or evacuated from a small enclosed space, that space experiences lower pressure. Because of the lower pressure in a small area, the atmospheric pressure outside pushes down on it and holds it firmly in place. Suction cups will hold on until either the cup is lifted from the side allowing air in and makes pressures equal or by applying a force large enough to overcome atmospheric pressure.

Thank you so much I was not able to get this topic so nicely but now I will be able to get 20/20 wish me luck !

[@acesensei6742]

I really like the simplicity of something like this

[@catty324]

great and easy to follow explanation!

[@TomWinkler-mz9yp]

If the dish and mirror are on the table then how does the initial pulling work? There is no air on the other side of the mirror to push it against the vacuum in the sucker

[@ca19788]

Can it stay stuck indefinitely or at some point it releases itself without having to lift the edge?

[@kollurusaharsh722]

Very very nice explanation now I can do my activity very well and submit it to sir .. tq a lot

[@sabakhan-qc9di]

Can you explain this with the formula please? Pressure= Force/Area

[@mkeppitipola]

can we do this with other materials and will this ever work on skin if you spend enough time designing it??

[@Rafay22637]

Your English is so much good 👍

from where can i get these

[@pujasaithandavan4365]

Nice explanation!

[@nikhilsimhambhatla3809]

This was very well done!

[@opium32]

What I wanna know is... Air pressure is 14PSI yeah? So on a sucker with a surface area of one inch, why isn't 14 pounds enough to pull it? Or if you had a larger sucker, why isn't 14 pounds or more enough to start to create a volume of space under vacuum? I mean conceptually it makes sense that you can't pull something apart without introducing something in between, but how do you explain this scientifically? What's the force holding them together if is greater than simply the atmospheric force? A vacuum doesn't have any mass, so why can't it be created in a volume under a sucker? It's not like it's creating air out of nothing, it's just the sucker material moving away from the surface material with nothing in between...

Good Explanantion Sir

Thank you.i needed this,im making coffee table with a big glass,40cm by 1m.im wondering if it can last years holding that glass

Is it OK to say that this video "sucks" ?
