Freefall position graph2/28/2023 ![]() More accurate than Galileo's water clock. Although you will be using an electronic stopwatch, it is not much To draw a "best fit" or regression line of experimentalĭata.You will discover that reaching conclusions about motion is not as easy as it Will test three hypotheses relating to motion on an incline. To reproduce Galileo's results using the inclined plane. This is not too unreasonable in a drag free world (with only gravity) your ball would take 89.21 seconds to fall to the ground, and the effect of drag is significant.Īll that being said, there will obviously be some inaccuracies that can be reduced by reducing the size of dt.INTRODUCTION In this experiment you will attempt ![]() Obviously, since your item has yet to reach its terminal velocity, it has fallen a lot more. From these outputs, you are still at 20000 m after 200s.Īt a terminal velocity of 40 m/s, after 200s your ball would've fallen 8000m. You would expect the height to decrease much faster. Given your numbers, the terminal velocity is about 40.4. The answer to this is pretty much the same as the previous: The velocity is never truly constant, but comes arbitrarily close to a value called the terminal velocity. The velocity should eventually become constant since acceleration will eventually be 0 and stay zero since the gravitational force is equal to the drag force. The velocity keeps increasing pretty fast even though the acceleration is roughly 0. In short, the limit of the acceleration as time approaches infinity is 0. This is a consequence of differential equations, which you should look up but can be explored in part here. Mathematically, the force of drag becomes arbitrarily close to the force of gravity, but is never exactly equal. The acceleration becomes rougly 0 eventually but it is not exactly 0, even though mathematically it should become 0 and stay 0 once the two forces are equal to each other.
