Some questions to Focualt Pendulam

 SOME CROSS QUESTIONS TO FOUCAULT PENDULUM 

What is the Foucault Pendulum?

The Foucault pendulum is a long, heavy pendulum that can swing freely in any vertical plane. It was first demonstrated by French physicist Léon Foucault in 1851.

Its purpose:

To show that the Earth rotates, using only a swinging pendulum and no reference to the sky.

How it Works

When the pendulum is set swinging in one direction (say, north-south), it keeps swinging in that direction due to inertia — it resists any change in motion.

But as the Earth rotates underneath it, the plane of the pendulum's swing appears to rotate over time.

This apparent change in direction is not caused by the pendulum itself turning, but by the floor (and the Earth) rotating beneath it.

However Here are some questions for all to answer 

 It is presumed that ,though the top hook from where the Pendulum is fixed as well as the ground rotates along with Earth ,the Pendulum does not ,(due to inertia )

Now my question are

1) How and why pendulum is not affected by Earth rotation. All things rotates along with Earth say

a)Top hook

b)Bottom ground

c)The Air,atmosphere 

 d)The man giving a push to pendulum. 

(By the way there is no animation available as per Chat GPT ,that shows all three mentioned above are rotating with Earth but the Pendulum is not rotating/affected.

2) Suppose we have a helicopter hovering over Mumbai, steadily for 12 hrs.The question is ..

Whether it can land in USA after 12 hrs ,as Earth below will rotate 180 degrees in 12 hrs?

Ok

Let us talk of inertia..

3) Suppose a plane takes off from. Terminal T2 of Mumbai and fly in the direction of rotation of Earth.( speed of Esrth rotation is 0.45 km per seconds)

The question is..

Whether,Due to inertia of moving plane ( like Focualt pendulam) the plane is not affected by Earth rotation

Though inertia of plane does make plane indifferent to Earth rotation ,how Focualt pendulam is an exception ?
