Gaya Gesek Orang Berjalan

Posted by Unknown - - 0 komentar



SELAMA kita berjalan ke depan, diperlukan arah gaya gesek ke depan. Untuk melangkah maju, kaki kita perlu mendorong lantai ke arah belakang.

Jika tidak terjadi pergesekan antara kaki dan lantai, maka kita akan terpeleset. Untuk menghindari terjadinya terpeleset, perlu adanya gaya gesek.

Akibat dorongan kaki ke belakang, maka arah gaya geseknya ke depan (berlawanan dengan dorongan kita). Kaki mendorong lantai ke belakang, lantai mendorong kita ke depan. Begitulah teori yang bisa Anda dapatkan dalam proses pergerakan berjalan.
