Cheat Sheet

  1. Gauss's Law in Electrostatics -

    As highlighted by HyperPhysics (Georgia State University), ∮E·dA = Q_enclosed/ε₀ elegantly links electric flux to charge - practice by sketching Gaussian surfaces around simple charge distributions. Remember the mnemonic "Flux Flows from Charge" to recall how field lines intersect surfaces proportional to enclosed charge. This foundational principle often pops up in electricity and magnetism quizzes, so visualizing symmetry can boost your speed and confidence.

  2. Maxwell's Equations Overview -

    According to MIT OpenCourseWare, the four Maxwell's Equations (∇·E=ϝ/ε₀, ∇·B=0, ∇×E+∂B/∂t=0, ∇×B−μ₀ε₀∂E/∂t=μ₀J) unify electric and magnetic phenomena into one framework. A handy mnemonic - "Divergence and Curl, From Charge and Current, Fields Swirl" - helps you recall their order and meaning. Mastery of these equations is a must for any advanced physics quiz online, so work through differential and integral forms to solidify your understanding.

  3. First and Second Laws of Thermodynamics -

    Drawing on resources from the University of Cambridge, the first law ΔU = Q − W enforces energy conservation, while the second law asserts that entropy S never decreases, ΔS ≥ 0 for reversible processes. Use the Carnot cycle example (η = 1−T_cold/T_hot) to see how efficiency ties back to thermal physics quiz concepts. A simple phrase, "You Can't Win, You Can't Even Break Even," helps you recall the impossibility of 100% efficiency in heat engines.

  4. Quantum Particle in a Box -

    As presented in Griffiths' Introduction to Quantum Mechanics, a particle confined to a one-dimensional well has quantized energy levels E_n = (n²h²)/(8mL²), where n is the quantum number. Think of this like discrete frets on a guitar - only certain "notes" (energies) are allowed. Testing this concept can earn quick points on physics trivia questions about wavefunctions and boundary conditions.

  5. Time Dilation in Special Relativity -

    Based on Einstein's postulates and NASA's relativity primers, time dilation is given by t′ = γ t with γ = 1/√(1−v²/c²), meaning moving clocks tick slower. Remember "Gamma = Get Away (from classical time)" to lock in the Lorentz factor's role. This cornerstone of relativity often features in advanced physics quizzes, so run through sample problems at various velocities to feel its dramatic effects.
