In the last case of floating ball, would the ball execute shm if displaced slightly?

[@nikhilkumarsingh9466]

Yes 👍

[@Ka161Rs]

Does the Magnus Effect apply to chargeless particles like photons and gravitons?

[@physicsgalaxyworld]

Magnus Effect is not directly related to charged or charge less particles... however photons and gravitons change the direction of motion due to another reason which you study in general theory of relativity or effect of gravity on momentum... not right now in the scope of these video lectures...

Sir the pressure-velocity trade off is only for points at same horizontal level or at same heights but in your example of plane wing two points are at different horizontal level

[@physicsgalaxyworld]

compared to altitude of plane level wing width is negligible...

Sir why Py>Px as X and Y are not at same horizontal level?

In tube initially there is air and no effect is considered due to gravity on air or gases...

Sir, in an atomizer why is Py>Px?

[@anmolempire1197]

For simplicity you can verify it by Px=Po Py=Po+g.h.ro Clearly Py>Px

Sir I am able to under stand that why Pressure at Y >pressure at X if we apply pressure velocity trade off equation. But to apply that equation , X and Y must be at same horizontal level , which is not true here! Please Explain this

[@maharshart1089]

Bro it's 5 years what are you doing now

[@ayushsaxena1164]

Dear sir pls explain That when we press our household pipe to increase pressure the flow velocity of water also increses due to which we could water far plants in our home lawn. Why is this.???🤔

[@ishansoni5865]

APPLY EQUATION OF CONTINUITY.. WHEN YOU DECREASE THE CROSS SECTIONAL AREA ITS VELOCITY WILL INCREASE... HENCE IF VELOCITY IS INCREASED THEN PRESSURE AT THAT POINT IS DECREASE.. WE NEVER INCREASE THE PRESSURE WE JUST INCREASED THE VELOCITY THERE

[@Vikkykumar-bf3dm]

sir you are saying that the air which is above the airoplan is moving fast in comparison which is below the airoplane why ? please sir explain me

[@shivammaheshwari7760]

sir in atomizer why Px

[@physicsgalaxyworld]

As pressure of x is low... liquid will lift up...

[@enigmayah9080]

As Py is atmospheric pressure, And at x pressure px is low (because velocity is High) The air Will move from Higher pressure Py to lower pressure Px

[@santhoshreddy2139]

In plastic ball floating example when displaced right streamlines get closer at right so velocity more pressure less ... where I am wrong sir

[@classicalbhargav]

Why won't there be any grav. potential energy difference in example B and C?

There are assumed to be at same height w r.t. ground so mg(h2-h1)=0 ...like in a normal aero plane which is straight...

[@kathaknritya7271]

Sir why the density of streamline is directly proportional to the velocity?

[@adarshchaturvedi3498]

actually, streamline density do not give idea about velocity of fluid, its the other way around ...

[@dftba4055]

Why there are more streamlines above the plane as compared to downside??

[@abhishekshankar1136]

it is known as the coanda effect when an aerofoil moves through a fluid the stream of fluid tends to follow the curved (convex) surface more as compared to the flat surface

[@amitanshupattanayak9065]

sir, how does the higher density of streamlines above the airplane wing account for the higher velocity above the wing?

[@physicsgalaxyworld]

streamlines are just the representation of fluid velocity in any region... higher density implies more velocity... reason is already mentioned above...
