How did you determine the value of the 'acceleration due to gravity? Or rather, what is the acceleration due to gravity?
's acceleration of gravity is the value of the quantity that governs the motion of bodies falling toward the center of the Earth, just as attracted by the force of gravity exerted by the planet Earth. I could us studying and observing the fall of well-polished ball down an inclined plane, also well polished. We can describe it?
Therefore, the motion of the ball depends on the angle of inclination of the plane and simple measurements at different angles are able to calculate and obtain a value slightly less than what we now know (g = 9.8 m / s ²).
This occurs in the absence of friction, however, when the latter is what happens?
If the friction is not negligible, the acceleration can be calculated taking into account the component perpendicular to the inclined plane. Indeed, it is responsible for the presence of friction.
There can you please describe his experiment on an inclined plane?
With the experiment I changed radically inclined plane of the Aristotelian idea of \u200b\u200bmotion, focusing on speeding, a level of motion ignored by Aristotle and most of his successors. I said:-In a straight edge, or vogliàn current dir, of wood, about 12 long arms, and off to one side arm and half for the other three fingers, this was less a sunken trench width, slightly larger d 'a finger tiratolo dead-straight, and to have it clean and smooth, incollatovi into a tusk and glazed parchment to you, you made it down in a bronze ball hard, well rounded and clean. " With all these points I wanted to make negligible the effects of friction. Rise above the horizontal plane one end (of regulation) an arm or two at will, was left off for that channel the ball, noting that the time consumed in entire scroll, repeating the same note many times to make good the amount of time. Facts and establish precisely this, we did go down the same ball for only a fourth of the length of its channel, and measured the time of his descent, he was always punctual to be half the other. " Repeating the measurement for different distances, I deduced that the distance traveled is always proportional to the square of the time taken to travel. In other words, if times are represented by 1, 2, 3, 4, 5 ... the distances traveled are respectively represented by 1, 4, 9, 16, 25 ... This is the first description of the motion defined by my time on, "uniformly accelerated" ..
