How is the curvature of the wave function related to its energy?
Honestly confused as to how we're going to apply everything we learned
in this prelecture Also, could I please have a picture of black cats?
Nothing really, we need more dogs and less cats.

Newtons Laws and Work
For a single object of mass m:
F = ma = dp/dt
F dt= m dv = d(mv)
F v dt = m v dv
F dx
= d(mv2)
F dx = mvf2 - mvi2 = (KE)
For a system of objects, you could add Newtons Law Vectorially
M = mi with Ftot = F
Ftot = Macm = dpcm/dt Ftot

My last request is that you play the song "Happy" by Pharrell since everyone is
happy that Physics 214 is almost finished. Also, please make sure the music is

Why is it that we normalize the wave function, again? Also, do people usually do
better on the final than on the midterm, or the other way around?
Could you post exam questions so that we can see where we got wrong?
