## Student Learning Outcomes

• Students should be able to analyze kinematics of rigid bodies in three dimensions.
• Students should be able to model the relationship between forces and acceleration and energy and momentum.

## Description

Intended for engineering majors planning to transfer to four-year institutions. It covers the fundamentals of kinematics and kinetics of particles and rigid bodies. Topics include general and relative motion, force and acceleration, work and energy, and impulse and momentum analyzed in two and three dimensions. Provides an introduction to vibrations and oscillations.

## Course Objectives

The student will be able to:
A. Objects as particles: Derive and apply the relationships between position, velocity, and acceleration of a particle in rectilinear and curvilinear motion.
B. Objects as rigid bodies: Derive relations defining the velocity and acceleration of any particle on a rigid body for translation, rotation and general plane motion.
C. Newton's second law: Apply Newton's second law to analyze the motion of both a particle in rectilinear or curvilinear translation acted upon by forces and a rigid body in plane motion acted upon by forces and moments.
D. Work and energy: Apply the method of work and energy to engineering problems modeled as a single particle, a system of particles, or a rigid body in plane motion.
E. Impulse and momentum: Apply the method of impulse and momentum to engineering problems modeled as a single particle, as system of particles, or a rigid body in plane motion.
F. Coriolis acceleration: Recognize situations in which Coriolis acceleration in plane motion is applicable.
G. Impact: Describe the difference between direct and oblique central impact and eccentric impact.
