Gerak parabola adalah gerak yang banyak dijadikan sebagai model untuk pengajaran Fisika khususnya kinematika dalam hal penjumlahan kecepatan; dalam hal ini gerak lurus beraturan (GLB) dalam arah horisontal dan gerak lurus berubah beraturan (GLBB) dalam arah vertikal. Dalam kenyataannya, gerak parabola dipengaruhi oleh variabel lain yaitu adanya hambatan udara yang membuat trayektori lintasan tidak lagi berbentuk parabola dengan asumsi adanya gesekan udara. Tendangan Bola dengan melibatkan faktor spin akan membuat lintasan lateral berbentuk melengkung karena adanya Efek Magnus. Dengan menganalisa faktor-faktor yang berpengaruh dalam gerakan benda dan dibantu dengan software Modellus dan Excell, maka dibuat pemodelan untuk gerak benda.
