Kinetic energy has no mass and adds no mass as proven by the case of
gravity.

So, you admit relativity reduces to verbiage.

According to SR, mass is invariant, which means that
it doesn't change with with velocity.

You are stating a triviality which nobody dispute,
so you have neither proved nor disproved anything.

(That mass is invariant doesn't mean that can't change.)

The mass m of a body is not constant.

It varies with the body's velocity, according to the equation:

m = m0/ √ 1−v2/c2

where:

v is the magnitude of the velocity of the body
c is the speed of light in vacuum
m0 is the rest mass of the body.


The value m is known as the relativistic mass of the body.

The factor 1/ √1−v2/c2 is known as the Lorentz factor.

If you had anything on the ball or anything to bring to the table you
could have offered this argument given by Van Flandern:
"The Einstein Hoax" book p.306= "SR establishes that kinetic energy
possesses inertial mass"; "Since the ratio of gravitational mass to
inertial mass of various materials has been found to be identical to a
high degree of accuracy, it is to be expected that kinetic energy which
is bound to matter will be affected by the gravitational field to the
same degree as is the energy associated with the rest mass. This
conclusion follows from the fact that different portions of the rest
mass of various materals consists of the mass imposed by kinetic energy.
This kinetic energy is contained, for example, in the kinetic energy of electrons in their orbits, the thermal motion of atoms, and perhaps in
the resonance states of nuclear particles."

This argument fails because mass does not vary in different
gravitational fields.

The first sentence is not proven. Therefore that proof
only proves that if mass does not vary with gravity
id doesn't vary with velocity, either.

Correct. Heat the body, and its mass increases.

It varies with the body's velocity, according to the equation:

A bit confused? :-D

Above you said:
Therefore, mass does not change with velocity.
Which is correct.

   m = m0/ √ 1−v2/c2

m is not the mass of the body, it is the "relativistic mass".

where:

   v      is the magnitude of the velocity of the body
   c      is the speed of light in vacuum
   m0     is the rest mass of the body.

m0 is "the mass of the body".

The value m is known as the relativistic mass of the body.

Exactly!
So you knew that the obsolete "relativistic mass"
is NOT "the mass of the body".

Why do you then keep repeating the obvious triviality:
"the mass does not change with velocity" which nobody refutes?

Mass is a relativistic invariant.

Dr. Richard Hachel said: "One hippopotamus does not become two
hippopotamuses by changing the frame of reference."

If mass were a relativistic variant, the energy of a body would become E=2mc².sqrt(1+Vr²/c²).

Everyone knows this is false, and that E=mc².sqrt(1+Vr²/c²).

So, no.

Mass is an invariant.

It's strange, moreover, that idiotic scientists still write: m'=m/sqrt(1-v²/c²).

This is ridiculous and false.
It is energy that is relative to velocity, not mass.

There is nothing wrong in writing so. The symbol m' just denotes something
else than mass: it is the energy expressed in units of mass.

It is already a well-established fact that mass does not vary with
gravity.

If is not a fact. It depends on what is meant by "mass". But a
meaning that regard the mass of a body a constant as long as
the body remains unchanged is found to be better for the
intended purposes of the term.
