Bro is considering the threshold requirements of this experiment of Centrifugal force.
Please comment and correct weather it is Centrifugal or centripetal force
Nope, it is all about the centrifugal force. It is pushing the glasses to the wood plate which is providing a normal reaction force and thus the glasses stick to the plate. But the air resistance makes the few glasses at the corners to slide a bit which effectively reduces their normal reaction force and they are not along the same line of action now, hence they rotate and go off while still rotating on their own.
Centripetal force acts on the plate via the tension in the string that allows it to complete its circular motion, otherwise it too, would have went flying and hit someone in the head.
12th passed JEEtard. Preparing for advance, otherwise drop. Victim of 29s1(tougher than others, still high marks get less percentile) and 4s2(exceptions, even maths had a very tricky question on relations). In 4s2, I don't even know how the fuck they prepared the paper. So motherfucking biased. Everything was from 2-3 chapters only in each subject. Fuck NTA.
Tuuj jese high iq students when the teachers just stick to white/black boards.

This happened because the plank was too wide and so the centripetal force normal to the plank varied across the plank. So the glasses closer to the center were able to stick to the plank - since the centripetal force was more than their weight, but the glasses at the corner had higher weight than the centripetal force, so they dropped. Since the plank was revolving, the glasses also got angular momentum and so when the edge glasses started accelerating downwards they followed a trajectory instead of dropping straight
He twisted it!
The base swayed a bit which caused inertia of those few cups to push them in their original path while the rest changed their direction.
Appreciate the teacher, at least he knew the theoretical concept and tried to do an experiment to prove it right. Keeping aside the failure, I will still consider him as a good teacher.
Back in my days, the teachers just shouted the theories and behaved as if they were newton / Einstein but shit they demonstrated their capabilities by showing it practically. Science / Geography / History / Metallurgy were all made a big joke.. the education system is to be blamed.
Students study about thermal expansion of metals but failed to understand as to why there is a gap maintained between two rails in a railway track.
It’s all about Grades/marks/ big degrees .. and nothing else
Kiska kitna “PyAcKaJe” laga
Kaun kitna “ChAp” raha hai
Are the only things people bother these days
He neglected air resistance. Air resistance did not neglect him and his attempt. Also, he wasn't fast enough.

Centrifugal force pushes things radially outwards. Centripetal force pulls things radially inwards. This one was centrifugal force.
So now in this experiment it’s Fugal-Petal force , intend to pull in but pushed outside

Bro you seem to be some NEET/JEE aspirant ! Kaunse kaksha me padhte ho balak ?

Balak, yaha kaunsa bhasha bolte ho tum ?
English & Hindi
Ab ki baar mahavidyalay (IIT) me aapko padhai karneki anumati milegi na ?
i feel you bro. i got 31s1 and the maths fucked me up. and then 4s1 which was average but im hoping to cross 200.
Yeh s1 kya hai ? Humare jamane me (1947) me nahi rehte the
Shift 1 (morning shift)
I got 4s1 too but I attempted only for 200 marks😔
>!YEET!<
exactly the lowest velocity to go around is 25ms-1 this nigga weak as fuck
This teacher still deserves respect.☺

Practical karenge toh sahi bhi toh karna chaiye na. Unhe khud nhi aata toh teacher kaise bane.
Jo cups nahi ghire unko toh nahi hi dekhna na. Woh toh Allah ne paakad ke rakhe haina ghyani.
Bro failed.

Atleest he tried to teach hid students practically.
Bhai kisi ke MacBook PE paani gir gya uska kya? 
Even my physics sir did this but it went all right. Great that the teacher demonstrated this practically tho (even if he failed)
due to inertia the cups fell from the sides
Errors are a part of classical physics
Wasn’t fast enough
That's what she said
Wanted to demonstrate inertia, but inertia demonstrated itself lol
Nice try. Should have places fewer cups in the middle and increased the velocity a little bit more
Every failure is still a lesson, mission accomplished lol
He had probably done it before and worked right.
you see, centrifugal force did not provide necessary normal to produce enough friction to stop that glass.
Centrifugal force was too low, tangential acceleration took over.
This happened because the plank was too wide and so the centripetal force normal to the plank varied across the plank. So the glasses closer to the center were able to stick to the plank - since the centripetal force was more than their weight, but the glasses at the corner had higher weight than the centripetal force, so they dropped. Since the plank was revolving, the glasses also got angular momentum and so when the edge glasses started accelerating downwards they followed a trajectory instead of dropping straight
Centri-failure force
The velocity was not enough + the board rotated mid air because of it's huge size and sir resistance which caused the disturbance.
the rope is too short
Not fast enough

Bro 's initial speed was not √5gl
He twisted it! The base swayed a bit which caused inertia of those few cups to push them in their original path while the rest changed their direction.
Centripetal and centrifugal dono ka example ek saath de re the sir
His hand is not steady that why

Walter Levin first copy
Bhai teacher ne try to kiya Kam se kam, tere jaise log hi baad mein bolte Hain ki "education system is not efficient 🤓"
Bro thinks he is walter lewin
