On one side, the air moved in the opposite direction to the ball's spin, causing increased pressure, while on the other side, the air moved in the same direction as the spin, creating an area of lower pressure.
Pada satu sisi, udara bergerak pada arah yang berlawanan dengan putaran bola, menyebabkan tekanan meningkat, sementara di sisi lain, udara bergerak searah dengan putaran, menciptakan area bertekanan rendah.
