Rutgers PHYSICS 123: Analytical Physics IA
PHYSICS 123 (01:750:123) is the first half of Rutgers' calculus-based mechanics sequence for engineering and physics majors, covering kinematics, dynamics, energy, and momentum. It's a 2-credit course paired with 124 (Analytical Physics IB) to cover the full first-year mechanics arc.

What makes it hard
Don't let the 2 credits fool you: the workload and exam difficulty are out of proportion to the credit count, which is exactly why students complain about it. Exams demand setting up problems with calculus from scratch, and the workshop-style recitations assume you've genuinely done the reading and problems beforehand.
What you'll cover
- • Kinematics
- • Newton's laws and free-body diagrams
- • Work and energy
- • Momentum and collisions
- • Angular momentum and rotation
- • Heat and kinetic theory
The PHYSICS 123 study guide
How to study for Rutgers PHYSICS 123, step by step.
- 1
Budget hours like it's a 4-credit course
PHYSICS 123's 2-credit label is a trap; the workload and exam difficulty say otherwise. Block real weekly study time in your schedule from week one, before other courses claim it.
- 2
Arrive at workshops with the problems attempted
The workshop recitations assume you've genuinely done the reading and problems beforehand. Showing up cold wastes the most valuable contact hours in the course.
- 3
Set up every problem from a diagram
Free-body diagram, then coordinate choice, then the calculus, in that order every time. Exams demand setup from scratch, and formula memorization without setup practice reliably fails here.
- 4
Take old exams under real time pressure
Past Physics 123 exams show how far above the homework the exam difficulty sits. Timed runs expose both knowledge gaps and the pacing problems that cost careful students points.

FAQ
Is Physics 123 at Rutgers hard?
Yes. It's a known difficulty spike for engineering students, with exam demands far above what a 2-credit course suggests. Treat it like a 4-credit course in your weekly schedule.
Why is Physics 123 only 2 credits?
Rutgers splits first-year analytical physics into half-semester-style 2-credit chunks (123, 124), so the sequence's total credits add up across parts even though each part is intense.
How do I pass Physics 123?
Do problems from a diagram-first setup every time, attend the workshops prepared, and practice old exams under time pressure. Formula memorization without setup practice fails here.
