Subject: Re: [Phys-l] definition of gravity
You are in a rocket whose motors are producing precisely enough thrust
to cause it to accelerate at 9.8 m/s^2. You are standing on a scale on
the floor that reads the same weight that it does when used on the
surface of the Earth.
Question 1: Does anyone have any qualms whatsoever about calling what
you are experiencing a gravitational force that is every bit as "real"
as any gravitational force can possibly be?
Question 2: Does anyone have any qualms whatsoever about saying that
you find there to be a gravitational field of 9.8 N/kg directed toward
the floor of the rocket?
