  2. anybody else love these classic forum emoticons? They’re so corny yet I love them anyways. anyways, I was wondering. What’s your favorite feature of this site? Mine is the badge system, a bit generic but I love it nonetheless. My hope is to collect all the badges one day.
  3. Forever now solidified with the invention of the Gauss Rifle, which I anticipate will soon lead to magnetic food delivery systems. Don’t quote me on this.
  4. Hello all, you’re in for a treat with the first blog post in *checks notes* FIVE YEARS? Well, I suppose this will be relevant enough. I’ve discovered the site through my physics regents review book, and the big day is soon upon me: tomorrow, in fact, is my Physics regents. I hope I do well! I realize it isn’t a Monday, but I felt inclined to share. have a great day to you all, and enjoy this meme.
  5. This is Breaking Bad tier dialogue in the best possible way.
  6. I think you’re right, though I would need access to the Empire State Building and a cadaver to conduct such an experiment. I’m trying to decide what would be harder to get.
  7. Just my two cents. I think, some will go to the ground too, since most of the weight will "evaporate", i.e. burn, support structure will bounce back to where it was before the weight was placed on it. But yes most of it will fly away with the molecules, you can think of a dry ice put on a trampoline, trampoline will depress, those heavy pellets disintegrate turn into small peaces - CO2 gas molecules - and fly away and take bits of the potential energy with them and trampoline will straighten out.
  8. Iron man can’t fly with the technology he has based on flying physics. He has thrust and drag, but no lift. The flaps on his back provide maneuverability but no lift. He would need wings like the falcon to fly
  9. Great, I think i have visited this kind of a website name paintballly
  10. The largest damping force is the air resistance on the mat. "Fly mats" are mats made from 4 mm wide webbing on 10 mm spacing. Or made from pairs of string about 1.5 mm wide per pair on 4 mm spacing. The net effect is that it's a net. With over 50% holes. One thing you notice on first jumping on a fly mat: You don't lose energy as fast. If you are used to losing a third of your energy doing a doggie drop, and then do this same trick on a fly mat and get 90% of your energy back it will scare the pants off of you. Good mats are not stretchy. You want all the energy storage to be in the springs, which are better at returning it. Most elastics fabrics are very poor at returning energy -- 40-60% especially in directions not along the weave.
