Cornell PHYS 1112: Physics I: Mechanics and Heat
PHYS 1112 is Cornell's calculus-based introductory mechanics course, covering kinematics, Newton's laws, energy, momentum, rotation, and an introduction to thermodynamics. It's required for engineering and physical science majors, with labs and the curved evening-prelim format.
Fennie is independent and not affiliated with Cornell University. This is an unofficial study guide.
What makes it hard
Physics prelims test modeling, not formula recall: drawing the right free-body diagram and choosing the right principle for an unfamiliar scenario. Students who pattern-match homework hit prelim problems designed to break patterns. Rotation late in the course stacks every earlier concept, punishing anyone with kinematics or force gaps.
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
- • Introduction to thermodynamics
The PHYS 1112 study guide
How to study for Cornell PHYS 1112, step by step.
- 1
Train the setup phase deliberately
PHYS 1112 prelims test modeling: draw the free-body diagram, name the applicable principle, and justify it, all before computing. Practice that sequence explicitly on every problem, because that's where the points live.
- 2
Seek out unfamiliar problems on purpose
The exams are designed to break homework patterns, so practice from past prelims, recitation sets, and other textbooks. If every problem you've solved resembles the homework, you've trained for the wrong test.
- 3
Keep your calculus frictionless
Derivatives need to be fluent and integrals conceptually comfortable. Calculus friction on top of physics reasoning is a common reason students fall behind in the first weeks.
- 4
Bank extra time for rotation
The rotational unit stacks kinematics, forces, and energy at once late in the course. Going in with gaps is how strong starts become weak finishes, so review earlier units before it begins.

FAQ
Is PHYS 1112 at Cornell hard?
Yes. It's a core weed-out for engineering. Curved prelims test physical reasoning on unfamiliar problems, so homework pattern-matching isn't enough. Students who practice setting up varied problems from scratch handle it; formula memorizers don't.
How do I study for PHYS 1112 prelims?
Practice the setup phase deliberately: for each problem, draw the diagram, name the applicable principle, and justify it before computing. Then do unfamiliar problems (old prelims, different textbooks), since the exam's whole design is breaking your homework patterns.
What math do I need for PHYS 1112?
Calculus-level working knowledge, meaning fluent derivatives and conceptual comfort with integrals, taken alongside or before the course. The physics reasoning is the hard part, but calculus friction on top of it is a common cause of falling behind early.
