Gerak Berbentuk Parabola

Gerak Berbentuk Parabola. Benda yang dilempar ke atas dengan sudut tertentu , juga tersusun atas dua macam gerak dimana lintasan dan kecepatan benda harus diuraikan pada arah X dan Y. a. Arah sb -X (GLB) v 0x = v 0 cos q ( tetap ) X = v 0x t = v 0 cos q.t. b . Arah sb -Y (GLBB)
