Bagaimana Cara Kerja Kok

Kok adalah benda berbentuk kerucut kecil yang digunakan dalam permainan bulu tangkis. Kok terbuat dari gabus yang dilapisi dengan kulit. Berat kok berkisar antara 4,74 hingga 5,5 gram, dan tinggi antara 62 hingga 70 milimeter.

Saat kok dipukul, udara di sekitarnya akan terdorong ke arah depan. Hal ini menciptakan daerah bertekanan rendah di belakang kok. Perbedaan tekanan antara bagian depan dan belakang kok menyebabkan kok bergerak maju.

Bentuk kerucut kok juga berperan dalam cara kerjanya. Bagian depan kok yang runcing mengurangi hambatan udara, memungkinkan kok terbang lebih cepat. Sedangkan bagian belakang kok yang lebar menciptakan area permukaan yang lebih besar untuk mendorong udara.

Saat kok bergerak, bulu-bulunya akan bergetar. Getaran ini menciptakan hambatan udara tambahan, yang menyebabkan kok melambat. Namun, getaran bulu juga membantu menjaga kok tetap stabil di udara.
