C615 Physics: Content Knowledge is the Western Governors University course that covers the advanced physics a secondary physics teacher is expected to know.
WGU's M.A. Science Education (Secondary Physics) program guide lists its topics as the nature and impact of science and engineering, principles and models of matter and energy, mechanics, electricity and magnetism, waves, and science teaching and pedagogy.
The guide also states that graduates verify their physics knowledge by passing the physics content knowledge test required to become a beginning teacher of secondary school physics.
That link to licensure makes C615 feel high-stakes. Success depends on fluent problem solving across every area of physics, not just familiarity with the ideas.

Key Concepts with Worked Examples
Energy Conservation
Many mechanics problems are fastest with energy rather than forces. If friction is negligible, potential energy lost equals kinetic energy gained.
Example: A 2 kg ball is dropped from 5 m. Its speed just before landing comes from mgh = ½mv², so v = √(2gh) = √(2 × 9.8 × 5) ≈ 9.9 m/s. Mass cancels, which is a useful teaching point in its own right.
Circuits and Ohm's Law
Ohm's law (V = IR) and the rules for series and parallel resistors underpin most circuit questions. In series, resistances add; in parallel, the reciprocals add.
Example: Two 6 Ω resistors in parallel give 1/R = 1/6 + 1/6, so R = 3 Ω. Across a 12 V supply, the total current is 12 / 3 = 4 A, split equally at 2 A per branch.
Wave Relationships
Wave speed equals frequency times wavelength (v = fλ). For a sound at 340 Hz in air at about 340 m/s, the wavelength is about 1 m.
Typical Assessment Work and How to Prepare
WGU assesses competency through performance assessments or objective assessments. Check your course page for the current format. Physics review typically involves:
| Activity | What it tests | How to prepare |
|---|---|---|
| Quantitative problems | Correct equations and units | Practice timed sets by topic |
| Conceptual questions | Understanding without calculation | Explain answers in words first |
| Graph analysis | Reading motion and other graphs | Link slope and area to physical meaning |
| Teaching scenarios | Pedagogy and misconceptions | Know common student errors and fixes |
Common Misconceptions to Master
Teacher-focused physics often tests whether you can spot and correct student misconceptions. Know these well:
- "A force is needed to keep things moving." Newton's first law says no net force is needed for constant velocity.
- "Heavier objects fall faster." Without air resistance, all objects accelerate at the same rate.
- "Current is used up in a circuit." Current is the same throughout a series circuit; energy is transferred, not charge.
- "Heat and temperature are the same." Temperature measures average kinetic energy; heat is energy transferred.
Science Teaching and Pedagogy
Pedagogy is part of the official topic list for C615, so expect to think as a teacher as well as a physicist. Physics education research has shaped several widely used approaches:
- Elicit, confront, resolve. Ask students to predict, test the prediction, then discuss why the result differed from their expectation.
- Multiple representations. Move between words, diagrams, graphs and equations for the same situation.
- Inquiry labs. Let students design part of an investigation instead of following a recipe.
- Safety. Electricity, lasers and moving objects all need clear risk management.
Example: To address the idea that heavier objects fall faster, a teacher asks students to predict which of two balls of different mass lands first, then drops them together. The near-simultaneous landing creates the moment of surprise that opens a discussion of gravity and air resistance.
Electricity and Magnetism Essentials
Electricity and magnetism is often the least practiced area. Make sure you can explain these core links:
- A moving charge or current produces a magnetic field.
- A changing magnetic field induces a voltage (Faraday's law), the principle behind generators and transformers.
- Electric field strength relates to force on a charge (E = F/q).
- Power in a circuit is P = IV, which connects electrical and energy topics.
Practice the right-hand rules with sketches until field and force directions are quick to find.
Where Students Get Stuck
- Unit errors. Convert to SI units before substituting.
- Formula hunting. Identify the principle first, then the equation.
- Weak electricity and magnetism. Fields and induction are often the least practiced area.
- Rusty maths. Revise trigonometry, vectors and rearranging equations.
Study Tips for C615
- Keep a formula sheet you build yourself, with a note on when each equation applies.
- Do mixed practice sets once topics are reviewed, so you learn to recognize problem types.
- Explain each answer aloud as if teaching a class.
- Check your program guide for the current content test requirement for your state.
