Inertial Frame of Reference and Wobbling of Earth
Eng. Kanthar Balanathan
During our student period in the early days, we studied that the earth has a spin. This spin is referred to as the earth's wobble. We also studied of Inertial Frame of reference in Applied Mechanics/Physics. The velocity of the peripheral point at the equator is 1,674 kilometres per hour. Unless otherwise a tangential external force is applied on the earth it will remain in motion and at a peripheral velocity of 1674km/hr, depending on the direction of the force which may cause the peripheral velocity to decrease or increase.
The wobble also depends on the external forces. Scientists have found out that several forces cause the earth's wobble to increase or change. E.g. water. Earthquakes etc.
“Wobble” may precede some great earthquakes, a study shows. Quote: https://news.osu.edu/wobble-may-precede-some-great-earthquakes-study-shows/
How about extracting oil from the earth in millions of gallons?
Russians bombing countries in latitude locations (e.g. Ukraine) can cause a tangential force due to Newton's third law, every action will have an equal and opposite reaction.
Countries testing nuclear bombs under the earth at latitude locations can also cause a shift in the wobble. The nuclear thoughtless, imprudent North Korean Leader Kim Jong Un is interested in nuclear assets and declares that he will wipe out certain countries. Does he know that his citizens are dying with no nourishment?
Therefore, practically, humans are destroying the planet Earth. Is this due to their ignorance megalomaniac attitude, absurdity or foolishness?
For what reason are we Spending trillions of dollars on space exploration? When we know crystal clear that we humans are destroying the planet.
Within this underperformance, humans are fighting for equal rights and against discrimination and oppression. Even minorities are standing up against the majority as equals. Language rights, cultural rights, etc. A study in anthropology will unravel the shortfalls.
The author's view is that humans suffer from a knowledge deficit and enjoy a megalomaniac attitude because of technology and wealth. Applied Physics and Astrophysics are top subjects that all have to study, understand, and enjoy. A complete understanding of our planet, Applied Physics, and environment is vital for human cohesive existence.
The Sri Lankan President obtained a bachelor’s degree in physics from a Sri Lankan University. No wonder President AKD understands the value of cohesion, interconnection, interrelation, structure, solidity, consistency, and unity. We salute our President AKD and pray that he will govern Sri Lanka for the next fifteen years.
Our Prime Minister Dr Harini Amara Suriya has a doctorate in Social Anthropology, and we are cheerful and contented that SL has been blessed with a top intellectual governing team. May God bless our governing team.

In classical physics and special relativity, an inertial frame of reference (also called an inertial space or a Galilean reference frame) is a frame of reference in which objects exhibit inertia: they remain at rest or in uniform motion relative to the frame until acted upon by external forces. In such a frame the laws of nature can be observed without the need for acceleration correction.

When the Earth rotates on its spin axis — an imaginary line that passes through the North and South Poles — it drifts and wobbles. These spin-axis movements are called “polar motion” in scientific parlance. NASA scientists have computed that the measurements for the 20th century show that the spin axis drifted about 4 inches (10 centimetres) per year. Over a century, that becomes more than 11 yards (10 meters).
