From the law of universal gravitation, the force on a body acted upon by Earth's gravitational force is given by where r is the distance between the centre of the Earth and the body (see below), and here we take to be the mass of the Earth and m to be the mass of the body. Additionally, Newton's second law, F = ma, where m is mass and a is acceleration, here tells us … WebThe gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm = ‖ ‖.. In SI units this …

WebThe conclusion is that the gravity inside Earth depends roughly linearly on the distance from the center of the planet and density variations account for the deviations from linearity. An interesting way to visualize this is to … WebThe gravitational pull of the Earth is never zero; the force (and therefore the acceleration) decreases as you go further from the Earth like 1 / r 2 where r is the distance from the center of the Earth. At altitudes equal to the radius of the Earth, 6378 kilometers or so, the force drops to 1 / 4 to what it is on the surface but it is not zero.
