If Minecraft uses real world projectile motion (without air resistance) then you should find the same vertical acceleration of the block. ![]() This will (in theory) give the projectile block a different initial velocity. Repeat the experiment in the video, but with a different number of explosive blocks.Here are some suggested experiments to further explore what is really going on here. What can you do? I say 'you' because I don't have Minecraft and I don't plan on playing it. Here is the data that is just near the center of the video (where the perspective issues shouldn't be too bad). I am sure they can count blocks, so there must be some perspective issues. Now, measuring the range, I get 119 blocks and not the 97 blocks stated in the video. When I started the analysis of the video, I used the tower to scale the video. I know the tower is supposed to be 43 blocks high and the range is 97 blocks. Well, my first guess is that there could be some perspective issues. ![]() What is going on here? For projectile motion with zero air resistance, this should be a straight line. I could clearly mark the start and the end of the motion along with some points right before it gets to the highest point. This is a little difficult since I can only see the projectile block (or what appears to be the block) for a few frames.įirst, here is a plot of the horizontal position of the block. Why else would he set the virtual camera perpendicular to the motion of the projectile? Perfect for – video analysis with Tracker. The robot creator of that video (I am guessing it was a robot based on the voice) clearly intended me to do this analysis. Video Analysisĭon't pretend like you didn't know this was coming. That is a bit closer, but really I am not satisfied. This would give a vertical acceleration of 8.5 m/s 2. If the length of the block was 0.5 meters, the starting position would just be 21.5 meters. I guess they used a time of 2.3 seconds instead of 2.25 seconds. ![]() This is slightly different than the value from the video.
