UMD PHYS 161: General Physics: Mechanics and Particle Dynamics
PHYS 161 is the first course in UMD's calculus-based physics sequence for engineers — kinematics, Newton's laws, energy, momentum, and rotation — followed by PHYS 260 and 270. It runs alongside the calculus sequence it constantly uses.

Build my PHYS 161 study planWhat makes it hard
Physics exams test modeling: choosing the right principle and drawing the right free-body diagram for an unfamiliar scenario. Homework pattern-matchers meet exam problems built to break patterns, and the rotation unit at the end stacks every earlier concept onto any gaps that survived.
What you'll cover
- • Kinematics in one and two dimensions
- • Newton's laws and free-body diagrams
- • Work and energy
- • Momentum and collisions
- • Rotational motion and torque
The PHYS 161 study guide
How to study for UMD PHYS 161, step by step.
- 1
Train the setup phase explicitly
Diagram, principle, justification — before any algebra. PHYS 161's exam points live in that sequence, so rehearse it deliberately on every practice problem.
- 2
Seek unfamiliar problems on purpose
If everything you've solved resembles the homework, you've trained for the wrong exam. Pull problems from old exams and other textbooks until novelty stops being destabilizing.
- 3
Keep the calculus frictionless
Derivatives fluent, integrals comfortable — the course leans on MATH 140/141 continuously, and calculus friction stacked on physics reasoning is how students fall behind early.
- 4
Bank review before rotation
The rotational unit re-uses kinematics, forces, and energy simultaneously at the end of the course. Review earlier units before it opens; gaps compound there.

Space the modeling reps with Fennie
Upload the PHYS 161 syllabus and Fennie's Daily Plan spaces problem practice so each concept is solid before the next stacks on it, with exam-synced review and quizzes generated from the actual course materials. It's free to start.

How Fennie helps with PHYS 161
Fennie's Daily Plans space PHYS 161's practice so each mechanics concept is solid before the next stacks onto it, with review synced to exams and rotation given banked time. Chat through setups — which principle, why, what the diagram shows — because setup reasoning is exactly what the exams isolate.
FAQ
Is PHYS 161 at UMD hard?
It's a genuine engineering gateway: exams test physical reasoning on unfamiliar problems, so homework pattern-matching isn't enough. Students who practice varied setups from scratch handle it; formula memorizers don't.
What math do I need for PHYS 161?
Working calculus — fluent derivatives, comfortable integrals — typically from MATH 140 with 141 alongside. The physics reasoning is the hard part, but calculus friction is the most common early derailer.
What comes after PHYS 161?
PHYS 260 (electricity, magnetism, and thermodynamics) and then PHYS 270 complete the three-semester engineering sequence, each with an associated lab. The mechanics foundations here are assumed throughout.
