Gravity, Not Mass Increases with Velocity


There are controversies and misunderstandings with the term “relativistic mass”. So, alternative concepts must be considered. It is postulated herewith that the stronger force required to accelerate an object moving at a faster speed is due to the increase of its inertia. That ensues in a rise in the gravitational force required to pull that object, and thereby brings to an increase in the gravitational constant. In this paper a formula is derived to calculate these variations in the gravitational constant, which is: . This makes the use of the term “relativistic mass” unnecessary.
