  1. I'm thinking the dog is a better way to go as well...

    Knee surgery

    Glad you're recovering quickly from your knew surgery!
  3. A couple years ago we actually did superconducting magnetic levitation in the classroom. I still have the kit if it's something you want to play with after the AP exam... it does require some liquid nitrogen, though, which takes a bit of work to procure. :-)
  4. Notice, too, that he uses a hook grip. Might make a great blog (or series of posts) about the hook grip and why it's so effective! Might also do a post on the snatch -- MUCH more challenging from my experience!
  5. Physics of Video Games has been a hot topic in the physics area for some time. Check out this post by pal Rhett Allain! https://www.wired.com/2010/10/physics-of-angry-birds/

    1 newton = 1 kg*m/s2, so... 1 N/kg = 1 kg*m/(s2*kg) = 1 m/s2
  7. Welcome to APlusPhysics -- hope your studies go well this semester!
  8. Absolutely. I can remember going to a class where we were on the range and a little old lady was learning to shoot and thought she'd be fine because she had a small little "pocket revolver," and was surprised how tough it was to control. Giving her a much larger semi-automatic, she found hitting the target was a piece of cake. Larger mass, smaller acceleration, easier to control!
  9. That is absolutely amazing... almost makes you think there had to be something wrong with the bat. Wouldn't believe it without seeing it!

    That's Dan Burns -- a rather well-known physics teacher on the west coast!
  11. Love the ongoing applications to baseball. Well done!
  12. Sounds like you're going to like the unit on gravity!

    CSI: Who Done it?

    It was a blast listening to the various folks talk out their reasoning, while watching others closely guard their secrets in an attempt to win the 'prize.'

    Homer Simpson

    I usually show this clip to my Regents classes each year -- love it!
  15. With your kinematic equations. Set up separate vi, fi, d, a, t tables for your two objects, and see what commonalities and relationships you can build based on the given information. Then, solve for vi of the object that starts on the ground (hint -- be careful picking whether you call up or down the positive y-direction. Either will work, but once you pick it, stick with it for the duration of the problem).
  16. Q: Two cats are on a roof. Which slides off first? A: The one with the smaller mew

    Tuba physics

    I heard someone tried dribbling a tuba down in the band room this week and caused some damage. Coefficients of restitution for band instruments are, apparently, fairly low.
  18. Vikings? Vikings? And I was just beginning to like you too...
  19. Tons of physics at the amusement park. I'm not a big fan of experiencing jerks (changes in acceleration), though my little girl loves it!
  20. FANTASTIC blog post, and a wonderful technology usage for us baseball fans!
  21. So what went wrong with the first attempt at calculating the horizontal displacement of the projectile?
  22. So why did the first attempt fail? What went wrong in your calculations?
  23. FizziksGuy

    Huston we have a problem

    So what went wrong with the first set of calculations?
  24. So what went wrong with the first set of calculations?
