The making of a champion: Shane Perkins can produce 2500 W of power and burns over 5000 kcal per day. That’s 21 million joules! Wow!
of course this vid of “Man vs. Toaster” can’t be overlooked. (at least by track cycling physics teachers)
A table of Some Specific Heat Capacities
Another table of Specific Heat Capacities of some metals
Conservation of Energy
The Ballistic Pendulum is a cool example of how the conservations of momentum and energy are used together to find the velocity of a bullet.
Work, Energy and Power
Here is the CrashCourse vid on WEP. It’s a good summary!
Note: we don’t have to worry about the vector stuff, or the calculus.
