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 conservation of energy.
What principle of motion can be inferred from Galileo’s experiment with the marble on inclined planes?

From Galileo’s experiment with the marble on inclined planes, the principle of conservation of mechanical energy can be inferred. The marble’s ability to reach the same height on the opposite side (when slopes are symmetrical) illustrates that its potential energy at the top is converted into kinetic energy as it descends, and this energy remains constant in the absence of external forces.
