We often hear that objects appear to be weightless in a spaceship circling round the Earth. In order to examine the effect in some detail, let us first define, what do we mean by the weight? The real weight of an object is the gravitational pull of the Earth on the object.
If, however, a satellite in a circular orbit is at an appreciable distance h above the Earth’s surface, we must take into account the experimental fact that the gravitational acceleration decreases inversely as the square of the distance from the centre of the Earth (Fig. 5.16).
“Gravity is mass affecting curvature of space”…Yes affecting what? Why two bodies of course One a black hole with (cough) “infinite mass”(splutter)…And a Sun- for instance.. Are you saying that a SUN winking out of existence (screaming x-rays) if it gets too close to a black hole… Isn’t information to those who detect it from Earth..?
