Course Objectives
- Critical Thinking
- Select an appropriate coordinate system (Cartesian, normal-tangential, cylindrical) and analyze the motion of particles and rigid bodies.
- Analyze the motion of particles and rigid bodies using different coordinate systems.
- Analyze the motion of bodies relative to translating and/or rotating coordinate frames.
- Use the equations of motion to compute the position, velocity, and acceleration of multiple points on rigid bodies in constrained motion.
- Construct free-body diagrams and apply Newton's Second Law to analyze the dynamics of particles and planar rigid body motion.
- Apply the work-energy principle, linear-impulse and momentum, angular-impulse and momentum, and conservation theorems (conservation of linear momentum, angular momentum, and energy) to particles and rigid bodies undergoing planar motion.
- Analyze the motion of impacting particles using impulse and momentum concepts.
- Quantitative Reasoning
- Calculate the mass moment of inertia of rigid body
