A scientific law is something that was been proven time and time again and in no instance has it ever been proven wrong. And gravity acts on everything in the universe in the same way and has never been proven wrong therefore it is a scientific law. Hope this helps!

The sailboat will be the give-way vessel or it will have the right of way always unless they are using the motor power of the sail or if the other boat cannot travel, then the sailboat would have to give way. Also, a sailboat will give the right of way to large ships that cannot maneuver. When a sailboat is in motor power, it will be measured as a power boat.
The forces of gravity between two objects are inversely proportional
to the square of the distance between them.
So the gravitational forces are stronger at closer distance, and weaker
at greater distance.
This is a big part of the reason why we are attracted more strongly to
the Earth than we are to Jupiter.
