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 ˇ°relativistic massˇ± unnecessary. %K Relativistic Mass %K Gravity Increase %K Mass Definition %K Inertia Related to Velocity %K Gravity Due to Inertia %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=59224
