IB Physics 1 Semester 1 Final Exam Review Assignment:

WebAssign

-The expectation is that you complete about 2/3 of the points that are possible. There are 133 points possible, and I’m expecting you to earn 88 points for full credit. Any that you earn above and beyond 88 will go towards extra credit assignment points. The assignment’s total score will be scaled before being entered in the gradebook—it will be entered as a 44 point assignment. If you do ALL the questions you will receive 53 points.

IB Physics 1—Semester 1 Final Exam Review Guide

Topic 1: Physics and Physical Measurement

-Orders of Magnitude—ranges, calculating, how to report them, using them in ratios for comparison of 2 things

-Metrics—units, prefixes and conversions, factor-label method, fundamental units vs. derived units, (and what are the fundamental units?)

-Random and systematic errors—what they are, how they can be reduced, examples

-Accuracy and precision (of measurements and of sets of data)

-Sig. figs!—reporting to proper precision, using sig. figs. In calculations to get proper answers

-Uncertainties—what they are and how to report them:

  • Absolute uncertainties—limit of reading vs. degree of uncertainty, how to determine experimental uncertainties
  • Relative (fractional) uncertainty—ratio of uncertainty to measurement
  • Percentage uncertainty—relative * 100 = %

-Propagation of uncertainties

  • Adding and subtracting: add absolute uncertainties
  • Multiplication and division: add percentage uncertainties
  • Then convert back into a proper absolute uncertainty

-Graphs

  • Recognizing manipulated and responding variables, putting them on the right axes
  • Determining the value of the slope
  • Determining the meaning of the slope and of the intercepts
  • Making and reading error bars
  • Best-fit lines and best-fit curves
  • Linearization of data

-Vectors

  • Examples of vector quantities vs. scalar quantities
  • Drawing vector diagrams
  • Addition of vectors
  • Drawing (graphical and parallelogram methods)
  • Determining resultant’s direction
  • Determining resultant’s magnitude
  • Vector components
  • Adding using the component method
  • Subtraction of vectors (adding a negativenegative vectors are opposite direction)
  • Relative velocity—in linear directions and 2-d

Topic 2: Mechanics

-Kinematics

  • Distance vs. displacement, speed vs. velocity
  • Average speed and average velocity, instantaneous velocity
  • Uniform accelerated motion—kinematic equations
  • Graphing motion—making the graphs, interpreting motion graphs
  • Displacement-time graphs, velocity-time graphs, acceleration-time graphs
  • Meanings of slopes? Integrals (area between line and x-axis)?
  • Free-fall—on earth, in a vacuum
  • Effects of air resistance (conceptual—not calculated)
  • Projectile motion
  • Horizontally launched projectiles
  • Projectiles launched at an angle

-Forces and dynamics

  • Mass vs. weight—calculating weight
  • Definition and Units of force; types of forces
  • Free-body diagrams (drawing and interpreting)
  • Newton’s 1st law of motion and concept of inertia
  • Equilibrium—static, translational, dynamic
  • Calculating forces when a system is in equilibrium
  • Newton’s 2nd law of motionF=macalculations and conceptual
  • Determining net force using free-body diagrams
  • Determining net force and/or acceleration using equation
  • Newton’s 3rd law of motion—identifyingaction and reaction forces
  • Friction—Static vs. dynamic; coefficients of friction

-Momentum and Collisions

  • Calculating linear momentum
  • Impulse-momentum theorem
  • Conservation of momentum
  • Collisions—elastic and inelastic, explosions
