Rumus hukum newton

  1. 1. HUKUM NEWTON 1. Hk. I Newton  Hk. kelembaman (inersia) : Untuk benda diam dan GLB   F  0   Fx  0 dan  Fy  0 2. Hk. II Newton  a  0  GLBB  F  ma  1   2  m1  m2 ahttp://www.banksoal.sebarin.com  1  T  m1  a 3. Hukum III Newton  F aksi = - F reaksi Aksi – reaksi tidak mungkin terjadi pada 1 benda 4. Gaya gesek (fg) : * Gaya gesek statis (fs)  diam  fs = N.s * Gaya gesek kinetik (fk)  bergerak  fk = N. k Arah selalu berlawanan dengan gerak benda/sistem. N=w N = w – F sin N = w + Fsin N = w cos  . Statika  F  0 : *  Fx  0 *  Fy  0    0 ---o0o--- ΣFx = resultan gaya sumbu x ΣFy = resultan gaya sumbu y ΣF = resultan gaya m = massa a = percepatan N = gaya normal μs= koefisien gesek statis μk= koefisien gesek kinetik W = gaya berat α=sudut yang dibentuk gaya berat setelah diuraikan ke sumbu x atau y
