MIT 8.01: Classical Mechanics

8.01 is MIT's calculus-based classical mechanics GIR — kinematics, Newton's laws, energy, momentum, rotation, and oscillations — required of every first-year student. Its OCW materials make it a benchmark mechanics course for self-learners and ambitious high schoolers worldwide.

Fennie is independent and not affiliated with MIT. This is an unofficial study guide.

What makes it hard

8.01 exams demand constructing solutions from physical principles — drawing the system, choosing the framework, executing the calculus — and famously catch students who excelled at plug-and-chug high school physics. Angular momentum and rotational dynamics late in the term are the standard grade-breakers.

What you'll cover

  • • Kinematics
  • • Newton's laws
  • • Work, energy, and conservation laws
  • • Momentum and collisions
  • • Rotational dynamics and angular momentum
  • • Simple harmonic motion

The 8.01 study guide

How to study for MIT 8.01, step by step.

  1. 1

    Practice setup-from-scratch daily

    8.01 exams grade your ability to construct a solution from physical principles — diagram, framework, then calculus. That generation skill, the one plug-and-chug high school physics never built, comes only from daily reps.

  2. 2

    Choose the principle before touching the math

    For every problem, write one line first: is this forces, energy, or momentum, and why? Principle selection is the highest-leverage habit in the course and the most common exam failure.

  3. 3

    Front-load rotational dynamics

    Angular momentum and rotation are the consensus grade-breakers, and they land in the final weeks when time is scarcest. Read ahead and start torque problems before lecture arrives there.

  4. 4

    Work OCW psets, then study the solutions

    Multiple OCW versions of 8.01 post psets with solutions — invaluable for self-learners and enrolled students alike. Attempt each problem honestly first; the solutions teach most when they're answering questions your attempt raised.

  5. 5

    Keep the daily sets coming with Fennie

    Upload the 8.01 syllabus or your OCW plan and Fennie's Daily Plan schedules daily problem sets that build setup skills ahead of each exam, with principle-selection quizzes generated from the actual course materials. Free to start.

How Fennie helps with 8.01

Fennie's Daily Plans schedule 8.01's problem practice in daily sets so setup skills build steadily ahead of each exam, on campus or through OCW. Chat through a free-body diagram that won't resolve, and generate concept-first practice questions that train principle-selection before computation.

FAQ

Is 8.01 hard?

It's a step up from even strong high school physics because exams require deriving approaches, not recalling formulas. Students who practice setup-from-scratch daily adapt; formula memorizers struggle.

Can I self-study 8.01 on OCW?

Yes — multiple OCW versions exist with lecture videos, notes, and psets with solutions. Pair it with 18.01-level calculus fluency for the full experience.

What's the hardest part of 8.01?

Rotational dynamics and angular momentum, by broad consensus — the formalism is new, the intuition is subtle, and it lands in the final weeks of the term.

Pass 8.01 with a plan, not a cram

More MIT courses

8.02 — Electricity and Magnetism

8.02 is MIT's electricity and magnetism GIR, covering electrostatics, circuits, magnetism, induction, and Maxwell's equations using multivariable calculus. It's the second required physics course for all MIT students and a heavily used OCW resource.

8.03 — Vibrations and Waves

8.03 is the third course in MIT's physics sequence — oscillators, coupled systems, waves on strings, sound, and electromagnetic waves through interference and diffraction. Its OCW versions, with full lecture videos and famously demonstration-rich teaching, make it a staple for physics self-learners after 8.01 and 8.02.

8.04 — Quantum Physics I

8.04 is MIT's first quantum mechanics course — wave-particle duality, the Schrödinger equation, one-dimensional potentials, tunneling, and the hydrogen atom. Allan Adams' OCW lectures for 8.04 are among the most-watched physics courses on the internet, drawing self-learners far beyond MIT.
