Which of Newton's Laws explains why satellites need very little fuel to stay in orbit?
Newton's first law of motion explains this
It is stated as,
An object either remains at rest or continues to move at a constant speed , unless acted upon by an external force.
Since, the satellites are in the space, there is no external force acting on the satellites.
Hence they need very little fuel to stay in orbit.
