The value of acceleration due to gravity $g$ on tThe universal gravitational constant $G$ has the SI value approximately:
The acceleration due to gravity at height $h$ aboFor a satellite of mass $m$ orbiting Earth at radius $r$ (from the centre), the orbital velocity is:
Kepler's first law (law of orbits) states that eaThe escape velocity from the Earth's surface is approximately ($R = 6.4 \times 10^6$ m, $g = 9.8$ m/s²):The universal gravitational constant G has approximate value:Newton's law of gravitation states the force between two masses is:At the surface of Earth, acceleration due to gravity g equals:At a height h above Earth's surface where h ≪ R, g' equals:
