相対性理論を理解する・・・・・・

0 名前：名無しさん：2005/10/08 09:55

私は中学生で、来年論文があるのですが、
物理関係に興味があります。
相対性理論か双子のパラドックスが面白いかなぁと思ったのですが、
中学生で理解できますでしょうか？

相対制理論は光信号のリザーブが移動すると最短距離に近く、遠ざかるってだけで証明問

393 名前：匿名さん：2024/10/07 14:01

重力について

重力については相対論よりも前のニュートンの球殻定理、水星の近日点の移動についてはすでに述べた。重力に関する等価原理などの相対論の主張に支持できるはない。反論できる相対論の主張には反論した。

394 名前：匿名さん：2024/10/10 16:16

重力について

「この地球の引力と遠心力の合力が重力の正体です」。これはあるウェブサイトからの引用。でも多くではこの引用文の引力が重力とされているのでは。引用文はその場逃れ、出まかせでは。

等価原理は受け入れ難い。ひとつには万有引力定数が慣性力にあって言及されているのを見た覚えがないこと。

395 名前：匿名さん：2024/10/14 15:28

等価原理

ある質点に働く重力(引力)と慣性力のそれぞれのベクトルのあり様に制約はないでしょう。よってこの二つの力の合力がゼロとなることもあり得ます。しかし特別なことではないでしょう。自由落下のエレベーターのように。

地表でわれわれに働く力は重力(引力)と遠心力の合力です。太陽系の惑星では固体、液体の表面における重力(引力)、惑星の自転の速度、遠心力もさまざまです。これでもまだ等価原理ですか。

396 名前：匿名さん：2024/10/20 12:14

等価原理(書き改め)

ある物体(質量 m) に働く重力は GmM/r^2 であり、慣性力は ma である。二つの力のベクトルが相殺されることは(現象として)禁じられていまい。自由落下中のエレベーターではある局所ではトータルで、他の局所では部分的に二つの力が相殺されている(現象として)。

数式の示すように二つの力は別ものである。リアルなエレベーターは等価原理を支持していない。

398 名前：匿名さん：2024/10/25 10:56

重力について(印象)

式、 F = GmM/r^2 は重力の働きをよく語っています。ただし、重力の伝播速度は光速とされていますが、実際は瞬時でしょう。太陽系の惑星のあり方に照らすならば。また、ブリタニカ国際大百科事典 1972-1975 の「重力」の項にも瞬時と。

重力については相対論者の眼中にはニュートンも現実もないようです。

399 名前：匿名さん：2024/10/29 11:32

自由落下

エレベーターが自由落下しています。エレベーターは質量 m の同じ質点から成り剛体とします。それぞれの質点は同じ加速をしています。それぞれの質点に働く慣性力は ma です。

この自由落下の説明に等価原理という言葉はありません。いや、あってはならないのです。

400 名前：ももんが：2024/10/30 15:59

重力と光の関係を表した式

401 名前：匿名さん：2024/10/31 11:31

等価原理

平面上(摩擦なし)に質量 m の物体が置かれています。この物体を張力 ma で右方へ紐で引きます。物体は右方へ加速し、慣性力 ma が左方へ働きます。張力と慣性力の大きさはイコールです。ニュートンの運動の第三法則の示すとおりです。

自由落下中のエレベーターで重力と慣性力の大きさが等しいのも(トータルとして)、ニュートンの運動の第三法則によるのでしょう。

402 名前：匿名さん：2024/11/01 09:49

自由落下

重力も慣性力も力のベクトルで示され得よう。自由落下のエレベーターで両者が打ち消される(現象として)のはあり得ることであろう。

しかし自由落下は両者のベクトルのかかわり方のひとつに過ぎない。自由落下が特別視されねばならぬ理由はあるまい。

403 名前：匿名さん：2024/11/05 11:15

第二宇宙速度(質問)

ケプラーの第三法則は惑星の公転速度は公転軌道の半径による(公転軌道が真円ならば)と。しかし第二宇宙速度の数式には地球の半径とのかかわりが記されています。この二つを統一的に説明した書物、ウェブサイトをご存知のでしょうか方ありましたらご教示ください。

404 名前：匿名さん：2024/11/13 08:31

自由落下

下方の天体に二台の同じエレベーターキャビンが自由落下しています。二台は上下に並び長い紐で結ばれています。紐のある所が局所慣性系？

405 名前：匿名さん：2024/11/15 13:42

自由落下

真珠のネックレスが縦一線となって自由落下しています。真珠それぞれに働く重力の大きさは mM/r^2 、慣性力の大きさは ma です。なお、真珠を連ねる紐の質量はゼロとします。

この投稿には等価原理への言及はありません。

406 名前：匿名さん：2024/11/18 10:45

自由落下(再び)

真珠のネックレスにあって重力の数式 G mM/r^2 、慣性力の数式 ma はそのままに働いているのでしょう。重力ではそれぞれの真珠に数式の示すとおりの大きさで。

特定の質点で重力と慣性力が全的に相殺(見かけ上)されるのも必然のことでしょう。

407 名前：匿名さん：2024/11/22 08:42

重力について

自由落下の思考実験ではエレベーターよりも真珠のネックレスがベターであろう。ほかにもあろうか。実例では 1994 年に木星に落下したシューメーカー・レヴィ第 9 彗星など。　

水星の近日点の移動の定説はお粗末。なおニュートンの球殻定理は再考されるべきであろう。

408 名前：匿名さん：2024/11/28 15:35

等価原理

重力も慣性力も定量的な把握をわれわれはなし得ているとできよう。しかし定性的な把握はなし得ていまい。このようなわれわれが等価原理を唱える資格があろうか。

いや、等価原理は直接的な否定ができるのかも。
