MCCCD Official Course Competencies
1. Build relationship between acceleration, velocity, and position to perform analysis in kinematics of a particle and rigid body in various coordinate systems. (I, IV, VI) 2. Relate accelerations and forces acting on particles and rigid bodies using Newton’s laws of motion in various coordinate systems. (II, III, IV, V, VII) 3.

Solve problems involving particle and two-dimensional rigid body kinetics using impulse-momentum methods. (II, III, IX)
MCCCD Official Course Competencies must be coordinated with the content outline so that each major point in the outline serves one or more competencies. MCCCD faculty retains authority in determining the pedagogical approach, methodology, content sequencing, and assessment metrics for student work. Please see individual course syllabi for additional information, including specific course requirements.
