-
Final exam preparation
- Start with Chapters 5-10 (because there is a midterm 2)
- Finding a Solution for Physics 1602 Special Relativity
pset 3

- Be careful because you can’t do the proof without this.
-
It seems important to have the idea that you can do a ^1/2 binomial approximation when looking at roots.
- It’s done everywhere.
E&M
- When differentiating , replace it with and calculate.
- It becomes .
- It’s quite important not to lose the direction information of vectors in the field. (blu3mo)(blu3mo)(blu3mo)
- Why prac exam 2e?
Things to memorize
- Beta transformation.
- Derivation of acc?

- In addition,
-
-
Thus, the acceleration in the x direction, as
-
seen in the primed frame, is reduced compared to that in the rest frame by three powers of γ, two from time
-
dilation and one from Lorentz contraction. However, the perpendicular components of the acceleration are only
-
reduced by two powers of γ– the ones due to the time dilation.

Not values but formulas
Integrate energy density over the entire space
-
C=Q/|Φ|
-
J=i/A
-
R=L/σ_c
-
C=ε_0A/d
-
E = λ/2πϵ_0r
