Question

Define the terms: i) escape velocity ii) Binding energy

Obtain an expression for binding energy of a satellite revolving around the Earth at certain

altitud​

Answer 1

Answer:

1)In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to eventually reach an infinite distance from it.

2)K.E. + P.E. The negative sign indicates that the satellite is bound to the earth by attractive forces and cannot leave it on its own. To move the satellite to infinity we have to supply energy from outside the planet-satellite system. This energy is known as the binding energy of a satellite.
