Course focuses on dynamics. Preceded by CIV100 — Statics. We used the Engineering Mechanics: Dynamics textbook by Meriam, Kraige, and Bolton.
The transition from statics to dynamics is definitely jarring, amplified by how terrible the Meriam and Kraige textbook is compared to the Hibbeler statics textbook. Give it some time, explore some different professors, and consider using the Hibbeler dynamics textbook.
Prof Sullivan has a supplementary video series on YouTube.
