Physics and Captain America’s Shield

NewImage

Fun, brain stimulating read from wired discussing how to make a model of Captains America’s shield using physics.

ONE OF CAPTAIN America’s signature moves is throwing his shield and having it hit its target after multiple bounces. It’s just what he does. But how difficult would this actually be? Yes, I know Captain America is just a comic book hero, but that doesn’t mean this won’t be a fun physics problem.

How do you model a thrown shield reflecting off different surfaces? Really, that’s the difficult part. Let me go ahead and start with some assumptions.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
