Praxis Physics 5266 Study Guide 2026–2027 | 200 Practice Questions

Prepare for the Praxis® Physics (5266) test with a complete study guide organized around the five ETS content categories. Each chapter condenses what the test measures into clear explanations, worked examples, summary tables, key-concept boxes, and labeled diagrams, so you can review mechanics, electricity and magnetism, waves, and matter and energy without hunting through a textbook.

This 140-page digital guide pairs a focused content review with two 100-question practice tests of exam-level questions, so you can practice reading data tables, interpreting lab scenarios, solving problems without a calculator, and judging how to teach a concept, the way the test asks.

What's Inside

• An overview of the current test: 125 selected-response questions in 2 hours 30 minutes, the five content categories and their weights (12/15/35/21/17%), scaled scoring, state-set qualifying scores, the on-screen constants table, fees, and retakes
• Nature and Impact of Science and Engineering: scientific inquiry, measurement and error, graph linearization, laboratory safety, engineering design, and the Science and Engineering Practices and tasks of teaching
• Principles and Models of Matter and Energy: atomic models, nuclear decay and half-life, binding energy, thermodynamics and heat engines, states of matter and gases, mass-energy, and quantum physics (photoelectric effect, energy levels, de Broglie waves)
• Mechanics: kinematics and motion graphs, Newton's laws, dynamics and circular motion, work, energy and power, momentum and collisions, rotation and torque, gravitation and orbits, simple harmonic motion, and fluids
• Electricity and Magnetism: electrostatics, fields and potential, capacitors, DC and RC circuits, magnetic fields and forces, Faraday's and Lenz's laws, generators, and transformers
• Waves: wave properties, standing waves and harmonics, sound and the Doppler effect, reflection, refraction, mirrors and lenses, interference and polarization, and the electromagnetic spectrum
• 26 labeled physics diagrams, worked examples, a formula and relationship quick reference, and a final review checklist
• Three-month, one-month, and one-week study plans, FAQs, test-taking strategies for a calculator-free test, and recommended resources
• 2 practice tests (200 questions, 4 answer choices each) weighted like the real test's five categories, with data tables, lab scenarios, and teaching tasks, plus a separate answer key explaining every answer
