No cable box required. 16 Experiment 3: Vector Addition Advance Reading Text: Motion in one and two dimensions, vectors and vector addition. Since the friction force is leftward (in the negative direction), the vector sum equation can be written as F net = F x - F frict = m • a. Working Model has been adopted by thousands of professional engineers to create and analyze real-life mechanical systems. The net force is the vector sum of all the forces. This study concerns finger force vectors during the torque production tasks.
