重力と宇宙のナビゲーション
連星系
⑴ 割合を求める
⑵評価
⑶変更方法
衛星軌道変更問題
単一の軌道変更
①軌道変更の瞬間:衛星の位置はほとんど変化せず、重力は変化せず、加速度も変化しない。
② 軌道の変化:衛星の加速:より大きな軌道に入る 衛星の速度が低下: より小さな軌道に入る
複数の軌道変更 (4つの速度の関係)
①まず2つの円軌道の速度を求める
② 2 つの単語の変化を結合して不等式を完成させます
宇宙ナビゲーション
第一宇宙速度 (最低発射速度) 7.9km/秒
衛星打ち上げ ①パワー:F000のみ影響を受ける ②運動:等速円
重力による加速度 (地球の自転は無視します)
第二宇宙速度: 地球の重力に打ち勝って地球を離れる (11.2km/s)
第三の宇宙速度:太陽の重力に打ち勝って太陽系を離れる(秒速16.7km)
惑星の動き
ケプラーの法則
第一法則: 太陽の周りのすべての惑星の軌道は楕円であり、太陽は楕円の 1 つの焦点にあります。
第 2 法則: どの惑星でも、その惑星と太陽を結ぶ線は、同じ期間に同じ面積を一掃します。
第 3 法則: 惑星の軌道の長半径の 3 乗と公転周期の 2 乗の比は等しい。
重力 (「月と地球のテスト」 - ニュートン)
式:F1000=Gm1m2/r² G=6.67*10-11乗(N・m²/kg²) 【キャベンディッシュ:ねじり実験】
適用条件:両方のオブジェクトをパーティクルとしてみなせる
特徴:①普遍性 ②巨視性 ③相互性
