Not a question but such a good clip for those that have not had the pleasure;
In summary: Moon's gravity through motion analysis of a video clip is possible but requires the frame rate, a known distance, and the number of frames between the release and impact of objects. However, this may be challenging without a video analyzer. The idea of using the YouTube playback time as the recorded time could be a good starting point. It is noted that the optics may affect the accuracy of the data. It is also mentioned that a measuring ruler would have been helpful for a more comprehensive experiment. In summary, calculating the Moon's gravity from this video clip would require accurate measurements and analysis tools.

To me the slower free-falling hammer than it does on Earth looks more fascinating, almost as if they are doing the experiment underwater.

Yr posts makes me wonder if it is possible to calculate the Moon's gravity by motion analysing this clip??
Need the frame rate and a known distance eg height of astronaut, their must be some object in view someone knows the precise length of??

With the frame rate, you will also need to know the number of frames between the moment of the release of the objects and the moment when they hit the ground, which I think is rather difficult to achieve unless you have some video analyzer to decompose the frames. For the first try may be we can just believe that the playback time is the same as the time the scene was recorded, i.e. use the displayed YouTube's time.

Yes that would be a good first calculation. I am worried that the optics seems a bit "squishy" ie distorted to get good distance data.
Why oh why did they not think to pack a 1m ruler.

cuz they don't/didn't know what a metre is/was
yeah some sort of measuring ruler would have been good to complete the science experimentD
1. How does the "hammer / feather moon drop clip" experiment work?
The hammer / feather moon drop clip experiment is a demonstration of Galileo's theory that objects of different masses will fall at the same rate in a vacuum. The experiment involves dropping a hammer and a feather simultaneously in a vacuum chamber, where air resistance is eliminated. In this environment, both objects will accelerate at the same rate due to gravity, resulting in them hitting the ground at the same time.
2. What is the significance of the hammer / feather moon drop clip experiment?
The significance of this experiment is that it helps to prove the concept of gravitational acceleration, which is a fundamental principle in physics. It also highlights the importance of eliminating external factors, such as air resistance, when conducting scientific experiments.
3. Has the hammer / feather moon drop clip experiment been performed on the moon?
Yes, the hammer / feather moon drop clip experiment was first performed on the moon during the Apollo 15 mission in 1971. Astronaut David Scott dropped a hammer and a feather from the same height and observed that they fell at the same rate, just as predicted by Galileo's theory.
4. Are there any factors that could affect the results of the hammer / feather moon drop clip experiment?
Yes, the experiment can be affected by external factors such as air resistance, which is why it is important to conduct the experiment in a vacuum. Additionally, the experiment may not produce accurate results on bodies with different levels of gravity, as the acceleration due to gravity varies on different planets and moons.
5. What other scientific concepts can be demonstrated by the hammer / feather moon drop clip experiment?
The experiment not only demonstrates gravitational acceleration but also the concept of inertia. Inertia is the tendency of objects to resist changes in their state of motion, and in this experiment, both the hammer and feather have equal inertia, causing them to fall at the same rate in a vacuum.
