The motion of an object thrown into space with uniform gravity will follow a parabola if air resistance is ignored. Consider the motion of an object with mass m (strictly speaking, a point mass) thrown in a direction that forms an angle of θ with the horizontal at a speed of v 0 ( The orbit of the mass is given by : y = x tan θ - g x 2 /2 v 0 2 cos 2 θ [Yasuhisa Abe] "Ability Physics: Movement of Objects" by Tetsuho Iijima, Takayuki Sasaki, and Takashi Aoyama (1999, Kyoritsu Publishing) [Reference] |©Shogakukan "> Parabolic motion (highest point and maximum point reached) [Figure...

一様な重力のある空間に投げ出された物体の行う運動で、空気による抵抗を無視した場合その軌跡は放物線を描く。 質量mの物体(厳密には質点)が、水平とθの角をつくる方向に速さv0で投げられた場合の運動を考察する( 質点が描く軌道は、xとyの式からtを消去して、xとyの関係を求め [阿部恭久] 『飯島徹穂・佐々木隆幸・青山隆司著『アビリティ物理 物体の運動』(1999・共立出版)』 [参照項目] |©Shogakukan"> 放物運動(最高到達点と最大到達点)〔図… 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
