Galileo’s thought experiment suggests that no net force is needed to sustain the uniform motion of the marble; an unbalanced (external) force is only required to change its motion.

If the right-side plane were ultimately made horizontal, the marble would continue to travel forever, trying to reach the same height from which it was released, assuming no friction is present.
As the right-side plane’s slope is gradually decreased, the marble travels further distances to reach the same height from which it was released.
From Galileo’s experiment, it can be inferred that in the absence of friction and other forces, the marble will conserve its mechanical energy, achieving the same height on the opposite side if the inclinations are equal, illustrating the principle of ...
If the angle of inclination of the right-side plane is gradually decreased, the marble will climb up to a lesser height compared to its initial height on the left side, because it will travel a longer horizontal distance before coming ...
