Question

what is binding energy of an orbiting satellite ????​

Answer 1

Answer:

Orbiting Satellites are bound to a particular planet because of a certain Kinetic and Potential energy associated with the Gravitational force of the planet.

Now , Binding Energy is the minimum amount of Energy required to take that satellite to infinity ( free from gravitational influence of the planet).

Mathematically, it refers to the opposite of Total Energy of a satellite.

Mathematical Calculation:

Kinetic energy of a satellite is

$KE \: = \frac{G(m1)(m2)}{2r}$

Potential Energy of the satellite is

$PE \: = \frac{ - G(m1)(m2)}{r}$

Total Energy is

$TE\: = \frac{ - G(m1)(m2)}{2r}$

Hence,

Binding energy is

$BE\: = \frac{ G(m1)(m2)}{2r}$

This amount of energy is required for freeing the satellite to infinity.

Answer 2

Answer:

The binding energy of a satellite can be defined as the minimum amount of energy required to be supplied to it in order to free the satellite from the gravitational influence of the planet (i.e. in order to take satellite from the orbit to a point at infinity).
