Physics 163 Second Semester Review

This web page provides links to online resources which will be useful for preparation for the second semester final exam. Each individual concept is categorized according to subject and linked to relevant pages at the GBS site. The number of questions pertaining to each subject category is listed in parenthesis. To perform well on the second semester exam, you will need to internalize the meaning of the listed concepts. These concepts will have to be utilized, applied and connected. In addition to this review sheet, there is also a series of practice questions with accompanying answers.

 

Unit 7: Einstein's Special Theory of Relativity (No Qs this year)

Two Postulates of Relativity

Time Dilation

  • Light clock thought experiment
  • Dependence of time measurements on reference frames and relative speed
  • Twin trip thought experiment w/flashing lights on traveling spaceship
  • Spacetime travel

     

Length Contraction

  • Dependence of length measurements on reference frames and relative speed
  • Equation and its use
  • Contraction in dimension of travel only

     

Relativistic momentum and kinetic energy

  • Dependence of mass upon reference frame and relative speed
  • Why objects cannot be pushed past the speed of light
  • Rest energy
  • E = m*c2 

 

Unit 8: Static Electricity (10 Q's)

Neutral and Charged Objects
  • Atomic structure: nucleus w/tightly bound protons and neutrons and electrons in an outer shell; only electrons can be added or removed by ordinary means
  • Using an electron/proton count to determine the charge (+, -, or neutral) on an object
  • Using the charge of 1 electron and the number of excess or deficient electrons to determine the charge on an object
  • Conductors vs. insulators

     

Charge Interactions

  • Opposites attract, likes repel, and neutral and charged objects attract
  • Polarization as an explanation of why neutral and charged objects attract
  • Coulombs' Law: equation, problem-solving, using as a guide to predicting the effect of Q or d on the force of electrical interaction

     

Charging an Object and Grounding an Object

  • Charging by contact - method; result; explanation
  • Charging by friction - method; result; explanation
  • Charging by induction - method; result; explanation; examples
  • Grounding a charged object such as an electroscope or an electrophorus plate; examples

 

 

Unit 9: Current Electricity (11 Q's)

Basic Circuit Principles
  • Two requirements for a circuit
  • Role of the battery in a circuit
  • Source of charge in a circuit

     

Mathematical Quantities in Circuits

  • Current - definition; units; symbol; direction of charge flow; comparison of i values at various locations about a circuit
  • Voltage (a.k.a. as "electric potential difference") - definition; units; symbol; comparison of V values at various locations about a circuit; relation to energy
  • Resistance - definition; units; symbol; cause of resistance; variables effecting amount of resistance
  • Power - definition; units; symbol
  • V = I*R equation
  • P = I*V=Work/time = I2*R equations

     

Ciruit Connections

  • Series connections - definition; effect of increasing # of devices in series upon total (equivalent) resistance, total current, bulb brightness, etc.
  • Parallel connections - definition; effect of increasing # of devices in series upon total (equivalent) resistance, total current, bulb brightness, etc.
