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
Yes, model rocket velocity can be accurately measured using various methods and tools.
Some common methods include using a stopwatch and measuring the time it takes for the rocket to travel a known distance, using a Doppler radar gun, or using an altimeter to measure the rocket's altitude.
The velocity of a model rocket can be calculated by dividing the distance traveled by the time it took to travel that distance. This can be done using the formula: velocity = distance / time.
Yes, there are several factors that can affect the accuracy of model rocket velocity measurements, such as wind conditions, launch angle, and the weight and design of the rocket.
Yes, measuring model rocket velocity can provide valuable data for improving rocket design, as it can help identify areas for improvement and optimize the rocket's performance.
