When we say we analyze bodies as particles, we mean that we only consider particles that are infinitesimal we consider their motion as an entire unit; we neglect any rotation about their own center of mass rotation is not negligible, we cannot neglect the effect rotation we assume that the body is infinitesimal small 2uestion 3 (1 point) The only variables we need to describe rectilinear motion (moving along a straight line) are time (t) and distance (x). With these we can define the particle's position and velocity, we need a third variable to completely describe the motion position, velocity, and acceleration, which completely describes the particle's motion. velocity and acceleration, we need a third variable to completely describe the motion position and acceleration, we need a third variable to completely describe the motion
