Gravity, Not Mass Increases with Velocity
... The inertia of a moving object is dependent on its mass and speed of motion. With increase of that energy it becomes harder to change the objects motion—acceleration, deceleration and deviation from its course. According to the main stream relativistic theory, this is due to the increase of the rela ...

... person is then split between the chains with the left chain holding 375 N – 62.5 N = 312.5 N and the right chain supporting 250 N – 62.5 N = 187.5 N or 3/5 of the tension in the left chain. This means if the person sits a distance x from the left end, they sit a distance (5/3)x from the right end. T ...
