So, 50 mS to drop that distance. Since an ISR can activate in around 3 uS (16000 times as fast as that) you should easily be able to detect even very heavy objects, like elephants, falling.
Sorry to sound like a smart aleck but speed of an object falling has no relation with the weight of object. Galileo showed this by throwing 2 balls of different weights from the Leaning Tower of Pisa
That is in a vacuum, wind resistance is a factor for one!
But you have to admit that foam blocks fall more slowly than elephants.
Make sure you film that.
Wind resistance is dependent upon surface area. And surface area has nothing to do with weight. So if u throw 2 balls of same dimensions, but one of steel and one of wood(as Galileo did) from the same height,
While this story has been retold in popular accounts, there is no account by Galileo himself of such an experiment, and it is generally accepted by historians that it was at most a thought experiment which did not actually take place.
Wind resistance is dependent upon surface area. And surface area has nothing to do with weight. So if u throw 2 balls of same dimensions, but one of steel and one of wood(as Galileo did) from the same height, they reach the ground at same time even though the steel one is obviously a LOT heavier. And this will work even on Earth's atmosphere because the wind resistance will be same on both.
QuoteMake sure you film that.Especially the part about getting the elephant to the top. Watch where you step.
Yes but Galileo didn't,
Sorry for diving off-topic, but the bit in bold above is untrue. The point of the thought experiment is that it only works in a vacuum, because as soon as you introduce atmospheric drag the net acceleration is determined by both weight and aerodynamic drag.
Subsequently, the amount of air resistance is dependent upon the speed of the falling object and the surface area of the falling object[\quote]Quoted from the above 2nd link.Guess you are right that this will not happen on earth. But acceleration is same for both balls(9.8m/s^2). It is not determined by weight or aerodynamic drag(best explanation: www.jimloy.com/physics/galileo.htm and links above). Instead, the heavier ball will accelerate for longer time, hence having more terminal velocity and striking ground first.
