Physics 1602 試験対策
20230503
Final対策
Chapter 5-10 をまずやる(midterm 2があるので)
pset 3
これ使えないとproofができないので注意
ルートを見たときに^1/2のbinomial approxが出来る、みたいな発想大事そう
至る所でやってるので
E&M
1/|x|の微分は、1/\sqrt{x^2}に置き換えて計算すれば良い
x/|x|^3になる
prac exam 2e なぜ
暗記もの
beta transf.
\frac{β - β_B}{1 - ββ_B}
acc 導出?
加えて、y = y - y_B
>Thus, the acceleration in the x direction, as

> reduced by two powers of γ– the ones due to the time dilation.
