The concept " minimum velocity at the bottom of the circular path required to complete a circle" explains this magic. Because in initial trials the water cup fell down as the velocity at the bottom was less than minimum velocity. But in the final trial the cup began to complete the circle as the velocity at the bottom exceeded the minimum required velocity.
Weight got converted into centripetal force. Zor se ghumana hai bas velocity zyada hogi toh problem nahi hai weight ke ilawa string ka tension centripetal force provide kar dega sir ko hath jamaye rakhna hoga.
in this action inertia, force are involved but this action main reason is circular motion that motion create inertia to kept the cup with force if u don't move with forcefully the cup is fell down
Fugitive is an English word that is used for a person who is running away from the law. CentriFUGAL force tries to pull the string away from the centre - like running away. You have to pull an object towards centre when it is trying to move away to keep it rotating. For eg: Gravity pulls the object towards the centre of eart.
Nicely explained sir. Physics is a beautiful subject. Always attracts me. Anything when puts into circular motion, experiences two types of force, one towards the centre, which is centrifugal and the other equal and opposite centripetal force, which is directed outwards. Since both are equal in magnitude, they neutralize each other, which keeps glass and water inside it fixed at one position (as the net external force acting on it is zero). This is the reason why earth is in motion round the sun.
The common misconception is that the two forces(centripetal and centrifugal) balance each other. Still, it should be noted that the centrifugal force is a pseudo force which is a consequence of considering motion from a rotating frame.
There are two components of acceleration one towards the centre and the other, tangential. And by Newton's 2nd law, Net Force exists along the direction where acceleration is non-zero( in easy words ) Abhi socho kidhar hoga Force !

Ok. What if you revolve it horizontally..... The glass may fall down.. Because the centrifugal force is horizontal and gravity is vertical force.. Glass can still stuck due to friction. But two forces at 90 degree will not counter each other.
I don't know sir whether I am right but I think if we wil rotate this system horizontally then the cardboard would rotate with some angular velocity(omega)as the glass here placed on the surface of the cardboard it would also rotate with same angular velocity(omega) so the Normal force between cardboard and glass which is acting towards the centre would provide necessary centripetal force and also there would be some force of friction acting upward(between glass and cardboard) which would balance the mg(glass's weight) which would be acting downward if we put all the thing and do some calculations then we would get an angular velocity (omega) that would be the minimum speed at which the system should be rotated to keep the glass from falling in horizontal case That omega would be Omega = ✓(g/mu×r) Where mu is coefficient of static friction And r is the distance of system's(glass along with cardboard) geometric centre and the whole system Thankyou Harsh verma🙂
Here's the science behind it: When something is spinning, it naturally wants to keep going in a straight line. But if you tie it to a string or rotate it in a circle, it's forced to change direction and move in a circular path. This change in direction creates a force that feels like it's pushing things outward, away from the center of the circle. So, when you're spinning a cup with water, the water inside wants to keep going in a straight line, but because the cup is spinning, it gets pulled towards the outer edge of the cup. If the cup is spun just right, the water stays inside because the force pushing it outward (centrifugal force) is balanced by other forces, like gravity and the cup's shape.
According to Newton's third law of motion,"every action has equal and opposite reaction" it means there are couple force i.e. centripetal and centrifugal which get neutralized and the force are in opposite directionnto each other
Respected Teacher, I am not a science student, but apart from centrifugal force, there must be center of gravity, which is pulling inside the circle. Thanks🙏

You have to pull an object towards centre when it is trying to move away to keep it rotating.

It's the inertia helped the glass to prevent it from falling

Ok. What if you revolve it horizontally..... The glass may fall down.. Because the centrifugal force is horizontal and gravity is vertical force.. Glass can still stuck due to friction. But two forces at 90 degree will not counter each other.
May be weight counter with friction
@@VSSVHK up to some limit only. But centrifugal force will do it's work eventually.
@@viveksinghchauhanbikingsin1425 yes but if body moves with constant speed centrifugal force balances normal reaction
@@VSSVHK which reaction. Centrifugal force will let the object thrown away if velocity or weight of object increases.
I don't know sir whether I am right but I think if we wil rotate this system horizontally then the cardboard would rotate with some angular velocity(omega)as the glass here placed on the surface of the cardboard it would also rotate with same angular velocity(omega) so the Normal force between cardboard and glass which is acting towards the centre would provide necessary centripetal force and also there would be some force of friction acting upward(between glass and cardboard) which would balance the mg(glass's weight) which would be acting downward if we put all the thing and do some calculations then we would get an angular velocity (omega) that would be the minimum speed at which the system should be rotated to keep the glass from falling in horizontal case
That omega would be
Omega = ✓(g/mu×r)
Where mu is coefficient of static friction
And r is the distance of system's(glass along with cardboard) geometric centre and the whole system
Thankyou

Centripetal force is due to tension in string. Centrifugal force is due to which force?
Its pseudo force , in order to explain Newton 3rd law
Written in the video title but anyways according to an observer watching from screen ,Centripetal force and tension
Yes.. and the frame of the cup is Centrifugal.
Accha centripetal force should act inwards n ...which force is balancing
@@ashishsankalp8512 normal and mg
well done :)
For glass as a system, inertia and normal
Net force of mg and normal is equal to the centripetal force (mv2/r)
Which force???
when we are travelling in a curved road in a vehicele , we feel that we might fall outward, which is nothing but a centrifugal force , but then why it is called a pseudo force
Sir centripetal or centrifugral force dono act kr rahi han .
Sir hamare liye Kya centrifugal force…ham to initial observer h hame to centrifugal nhi infact hame centripetal dikhega but water ki observation se dekhe to centrifugal dikhega….bcz wo Khud rotate kr rha h or ek rotating observer centripetal force nhi dekh skta
Centrifugal force is not force then how to visualise it ....
Centrifugal force
Super
But centrifigical force is not a real force, but fictive one, appear in non inertial reference
Riks???
Centrifugal force pushes the body, to the outer side, resulting in 0 waste of water.
Pseudo force caused by centripetal acceleration which is also known as centrifugal force.
