Document Summary
Vectors z > bx + by + bz > j i k = |a| b| * c os x = x2 x1 and y = y2 y1. A = ax + ay + az j. A b = ax i, a j, a k < y i j = 0 i k = 0 j k = 0. = 0 + a * t. 1 x = x0 + v0 + 2 at. F = m a t m1 1 = m2 2 a a. Apparent weight and freefall (with constant force) n = m + ay (g ay = g. Friction n fk = k fs s n. D 2 = m = m dt a v dv m k = m = m dt g a ir drag mg a v mg. Note: speed is a scalar quantity because it is the magnitude of a vector but not the direction.
