Answer 2

Answer:

Natural Satellites are the satellites which are not man made and they revolve around a planet.

E.g. Moon

Artificial Satellites are man made and they orbit around a planet for a specific purpose.

Any object thrown upwards comes back to earth because of gravity.

Gravity attracts the object toward the center of earth.

Artificial Satellites are launched with escape velocity.

Escape Velocity is the velocity required to escape the gravitational force of any planet.

For Earth, it is 11.3 m/s
