“Ball Rolling”
Thomas Kuhn reports, “Galileo found that a ball rolling down an incline acquires just enough velocity to return it to the same vertical height on a second incline of any slope, and he learned to see that experimental situation as like the pendulum with a point-mass for a bob. Huyghens then solved the problem of the center of oscillation of a physical pendulum by imagining that the extended body of the latter was composed Galilean point-pendula, the bonds between which could be instantaneously released at any point in the swing.” Here, Kuhn merges Galileo’s and Huyghen’s findings to illuminate the milestones regarding the exposition of velocity. The observations regarding the ball and the pendulum subsidized meaningfully to the suppositions regarding the repercussion of velocity.
Pendulum
Thomas Kuhn expounds, “Daniel Bernoulli discovered how to make the flow of water from an orifice resemble Huyghen’s pendulum. Determine the descent of the center of gravity of the water in tank and jet during an infinitesimal interval of time. Next imagine that each particle of water afterward moves separately upward to the maximum height attainable with the velocity acquired on that interval.” The imagery illustrates the repercussions of gravity on velocity. Bernoulli’s experiment is an extension of Huygens’s innovations; hence, it underwrites the accrual of scientific deductions regarding velocity and gravity.
