Nature of Orbits for a body projected from earth with different speeds

Minimum velocity required for an object to orbit around the Earth  is  Vs =√gR = 8KmSec⁻¹

Let Ve be the escape velocity  required for a body to escape Earth's gravitational field.

Let if  'V' be velocity with which a body is projected from Earth.

Then,

1. V < Vs → body falls to ground
2. V=Vs → body rotates round the Earth in circular orbit closer to surface of Earth.
3. Vs < V < Ve → body revolves in elliptical orbit
4. V=Ve → body just escapes from Gravitational Field
5. V>Ve → body moves in interstellar space with velocity equal to √❲V²-Ve²❳
6. V<Ve → Total Energy of body is Negative
7. V=Ve → Total Energy of body is Zero.

Does energy is associated with intrinsic inertia, the rest mass?

We could have the object-at rest-annihilate with an "anti-object", producing radiation possessing energy. so, yes there is energy associated with the rest mass.

While creating object, various particles like electrons, protons, neutrons are to be brought in together. Every bit of energy that goes into creating the object would be accompanied by an increment in inertia according to relation E = mC2

The attribute energy is always accompanied by attribute inertia.

In 1905, Einstein summarized his theoretical disclovery with the sentence,

" The mass i.e. inertia of a body is a measure of its energy content."

Energy in all forms has property of inertia, the reluctance to undergo a change in velocity. The more energy that went into forming a body, the more inertia the body has.

Is there energy associated with intrinsic inertia, the rest mass?

We could have the object at rest to annihilate with an "anti-object", producing radiation possessing energy.
So, yes, there is energy associated with the rest mass.

while creating an atom, various particles like electrons, protons, neutrons are to be brought in together. Every bit of energy that goes into creating the object would be accompanied by an increase in inertia.

According to relation E = ΜC^2

The following figure sketches this symbolically. Starting from zero for both the object's energy and its inertia and adding up increments, we emerge with E=MC^2.

The attribute energy is always accompanied by attribute inertia.

In 1905, Einstein summarized his theoretical discovery with the sentence,

" The mass [i.e inertia] of a body is a measure of its energy content."

Energy , in all forms has property of inertia, the reluctance to undergo a change in velocity. The more energy that went into forming a body, the more inertia the body has.
