To start with lets see how we feel this weight. If an object rests on a surface, its weight acts downwards on the

Orbital Velocity of Satellite-derivation of 3 expressions

Orbital Velocity of Satellite Definition: Orbital Velocity of a satellite is the minimum velocity it has to maintain to continue its circular motion in its orbit. We know for a circular motion to continue, a force called centripetal force is required to work upon the object in circular motion. And this force is a real
