Question, if i record a video of a model rocket launching, and then falling, is it possible to get the actual (or extremely close) velocity every 1 second?
thanks
thanks
If you know the distance, yes.LT72884 said:Question, if i record a video of a model rocket launching, and then falling, is it possible to get the actual (or extremely close) velocity every 1 second?
Distance between camera and launch site, then you'll need to measure the angle/change in angle.LT72884 said:total distance or the distance at each second?
thanks
15 feet is way too close. You'll want to be at least 100 feet. And it may not work with a single camera due to the short flight and need to cover a large angular motion - you probably cant move the camera during the flight. Maybe 2 or 3 cameras could work. Measure your camera's field of view, then sketch a diagram of how it would look.LT72884 said:ok, so if i am 15 feet from launch site and it goes 1100 feet and takes 3 seconds to fall. how do i get the velocity of the rocket at every second or half second?
i know a bunch of rocket equations, but im trying to get the information from the cameras.
thanks
This is only possible if the rocket were upside-down accelerating earthward. (And maybe not even then)LT72884 said:it goes 1100 feet and takes 3 seconds to fall
Or, if it's Felix Baumgartner inside the rocket!Vanadium 50 said:This is only possible if the rocket were upside-down accelerating earthward. (And maybe not even then)
If it's accelerating and covering 1100 feet in 3 seconds, it's not going to survive the landing,Rive said:which can survive the landing).

... I would most definitely not try that at homeLT72884 said:i am 15 feet from launch site and it goes 1100 feet
