Every time a new clip is released for Star Wars: The Force Awakens, I find something new to analyze. I really need to stop, but I can’t. In this video we see BB-8 getting tossed around inside the Millennium Falcon. Now for an analysis.
What would make BB-8 ride up the side wall of the Falcon? The answer is the same force that pushes you against the car door when you make a turn: nothing. There is no force that pushes you in this kind of motion. In fact, the car door pushes you when you turn but nothing is pushing you into the door. Why is this so? Let’s start with the Momentum Principle. This says that the net force on an object changes the momentum of an object.
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.
