How do we know how long a second is?
I am sharing this video because I found it interesting and think it is worth watching.
I recommend this video. Watching it is not required for an assignment; it may simply prompt useful ideas or questions about physics. If you have some time, take a look.
To complement our course work, I recommend the second Mechanical Universe episode on falling bodies.
I especially recommend this episode to accompany our current work. It addresses falling bodies, Galileo, acceleration, and the mathematical development of motion, connecting well with several concepts from this unit.
