UCLA PHYSICS 5A: Physics for Life Sciences Majors: Mechanics and Energy
PHYSICS 5A is the first course in UCLA's physics sequence for life-science majors and pre-meds, covering kinematics, Newton's laws, energy, momentum, and rotational motion with biological applications. It's the life-science counterpart to the engineering-focused 1-series, with lecture, discussion, and lab.

Build my PHYSICS 5A study planWhat makes it hard
The 5-series has a reputation for conceptually demanding exams that emphasize reasoning and applications over plug-and-chug, which surprises students expecting a gentler life-science track. Two midterms and a final inside ten weeks means an exam roughly every three weeks, and problem setup — free-body diagrams, choosing the right conservation law — is where points are lost.
What you'll cover
- • Kinematics in one and two dimensions
- • Newton's laws and free-body diagrams
- • Work, energy, and conservation
- • Momentum, impulse, and collisions
- • Rotation, torque, and angular momentum
- • Applications to biological systems
The PHYSICS 5A study guide
How to study for UCLA PHYSICS 5A, step by step.
- 1
Don't underestimate the life-science track
The 5-series exams are conceptually demanding and reasoning-heavy, not the plug-and-chug some students expect. Engage the concepts seriously from week one rather than coasting on the lighter math.
- 2
Solve problems daily — an exam lands every three weeks
Two midterms plus a final in ten weeks means exam season never stops. Daily problem work keeps you continuously ready instead of cramming three times.
- 3
Drill the setup ritual
Choose the system, draw the free-body diagram, pick the conservation law — before any algebra. Most lost points trace to setup, so practice that phase deliberately on every problem.
- 4
Audit your errors after each practice exam
Sort misses into setup errors (review concepts) and execution errors (drill mechanics). Re-derive the chapter's key results yourself rather than memorizing final formulas — derivation survives exam pressure.

How Fennie helps with PHYSICS 5A
Daily Plans structure PHYSICS 5A around its relentless quarter-system exam cadence, with problem practice scheduled daily so each midterm gets real preparation. Use Fennie's chat to drill the setup phase of mechanics problems — what's the system, what's conserved, what does the diagram look like — because the 5-series exams reward reasoning over formula lookup.
FAQ
Is PHYSICS 5A hard at UCLA?
It's harder than many expect from a life-science track — the 5-series exams emphasize conceptual reasoning and applications over plug-and-chug, and the quarter delivers an exam every few weeks. Treating the concepts seriously from week one is what separates outcomes.
Should I take PHYSICS 5A or the 1-series?
The 5-series is designed for life-science majors and pre-meds with lighter calculus demands; the 1-series is the calculus-based sequence for engineering and physical-science majors. Your major and pre-health requirements determine which sequence you take.
How do I study for PHYSICS 5A midterms?
Work past exams and unassigned problems under time pressure, and audit your errors — most lost points trace to setup, not arithmetic. Re-derive each chapter's key results rather than memorizing final formulas, since the exams reward reasoning.
