Thanks for your wishes.
According to this kinetic energy imparts mass. Kinetic energy is energy
that has no mass and imparts on mass. The relation is an unwarranted
inference from experiments.
In times of Newton, what existed to define "capability of action" was
what was called "vis viva", which was the modern concept of linear
momentum.

Newton's 2nd. Law introduced the concept of force as the "rate of change

momentum", which became F = d/dt(mv) = ma.

One century later, when the general concept of energy was discussed,
linear kinetic energy was defined as the power embedded into any object
in linear
trajectory due to accumulation of speed of a given mass, starting from
v=0.

The factor 1/2 is purely due to adoption of the result of the integral.
No
physical meaning. Only mathematical. In this way, linear momentum, KE
and force
were mathematically connected.

Nothing has changed for 300 years, even with the fucking relativity
except for
the unscrupulous use in particle physics.
