16 lessons

One lesson for each chapter of University Physics Volume 2, in the book’s order. The lesson teaches what that chapter says you need to know, then checks it.

  1. 1Temperature and HeatThe three phases of water (ice, liquid water, and water vapor) can coexist at a single pressure and temperature known as the triple point
  2. 2The Kinetic Theory of GasesThe ideal gas law can also be written and solved in terms of the number of moles of gas: p V = n R T , where n is the number of moles and R is the universal gas constant, R = 8.31 J/mol · K
  3. 3The First Law of ThermodynamicsA thermodynamic system, its boundary, and its surroundings must be defined with all the roles of the components fully explained before we can analyze a situation
  4. 4The Second Law of ThermodynamicsThe focus of a refrigerator is on removing heat from the cold reservoir with a coefficient of performance K R
  5. 5Electric Charges and FieldsThe electric charge of one electron is equal in magnitude and opposite in sign to the charge of one proton
  6. 6Gauss's LawThe electric flux through a surface is proportional to the number of field lines crossing that surface.
  7. 7Electric PotentialThe superposition principle holds for electric potential energy; the potential energy of a system of multiple charges is the sum of the potential energies of the individual pairs
  8. 8CapacitanceWhen several capacitors are connected in a series combination, the reciprocal of the equivalent capacitance is the sum of the reciprocals of the individual capacitances
  9. 9Current and ResistanceThe average electrical current I ave is the rate at which charge flows, given by I ave = Δ Q Δ t , where Δ Q is the amount of charge passing through an area in time Δ t
  10. 10Direct-Current CircuitsAll voltage sources have two fundamental parts: a source of electrical energy that has a characteristic electromotive force (emf), and an internal resistance r .
  11. 11Magnetic Forces and FieldsMagnets have two types of magnetic poles, called the north magnetic pole and the south magnetic pole.
  12. 12Sources of Magnetic FieldsThe magnetic field created by a current-carrying wire is found by the Biot-Savart law
  13. 13Electromagnetic InductionThe induced emf in a closed loop due to a change in magnetic flux through the loop is known as Faraday’s law.
  14. 14InductanceThe unit of self-inductance and inductance is the henry (H), where 1 H = 1 Ω · s
  15. 15Alternating-Current CircuitsDirect current (dc) refers to systems in which the source voltage is constant
  16. 16Electromagnetic WavesMaxwell’s prediction of electromagnetic waves resulted from his formulation of a complete and symmetric theory of electricity and magnetism, known as Maxwell’s equations
