Welcome to Physics 131! Course Goals – What do I hope you will remember five-years from now Spreadsheets and Computers The Philosophy Behind the Preparation Physics 131 – What IS Physics? How to Contact Us Class Sessions Welcome Letter What tools do you need? What do they cost? Why are we studying physics and what exactly will we be learning? What do I already need to know? How will this course be structured? What is the schedule? Within each unit, how will I be learning? There is a lot of discussion of teams above, how do teams work in this class? How Will My Grade Be Determined in This Course? Academic Honesty Introduction[footnote]This is a selection of sections taken from: Denker, J. Uncertainty as Applied to Measurements and Calculations. Uncertainty as Applied to Measurments and Calculations (2011). Available at: http://www.av8n.com/physics/uncertainty.htm. (Accessed: 26th August 2016) [/footnote] What About Significant Figures? Pedagogical Digression – Extreme Simplifications In place of the “sig figs” rules, you can use the following guidelines: Introducing Probability How would we know if it’s fair? A simple model for thinking about probabilities: a fair coin If we only care about the totals: microstates and macrostates Now, let’s move on to thinking about probability distributions beginning with discrete data. What is a factorial? The Stirling Approximation Factorials Combinations What is a Force? Another Useful Way to Think of Force: Pressure Mass (As Opposed to the Force of Weight) Work and Energy A Note on Units How Many Kinds of Energy Are There? Conservation of Energy[footnote]Flowers, P., Neth, E. J., Robinson, W. E., Theopold, K., & Langley, R. (2019). Energy Basics. In Atoms First 2e (p. 9.1). OpenStax.[/footnote] Matter in General The Phases of Matter Degrees of Freedom in Materials Temperature Scales and Reference Points Going from an Average to a Total Gravitational Potential Energy Potential Energy of Springs (Elastic Potential Energy) Where is Potential Energy Zero? (And Does It Matter?) Potential Energy and Conservative Forces Nonconservative Forces and Friction What is a Closed System Anyway? Examples of Conservation of Energy in Closed Systems Open Systems Ways of Transferring Energy: Work and Heat More on Work Heat Conservation of Energy in an Open System Dimensions of Space Time Measuring Dimensions – Space Section Summary Velocity Direction of Velocity Speed Touchstone Values of Velocity Section Summary Touchstone Values of Acceleration Acceleration as a Vector Section Summary Line graphs What you can read off a graph Summarizing the Physics Slopes and General Relationships Graph of Displacement vs. Time (a = 0, so v is constant) Graphs of Motion when a is constant but not equal to zero Graphs of Motion Where Acceleration is Not Constant Section Summary Two-Dimensional Motion: Walking in a City The Independence of Perpendicular Motions Summary Resolving a Vector into Perpendicular Components Calculating a Resultant Vector Adding Vectors Using Analytical Methods Summary Vectors in Two Dimensions Vector Addition: Head-to-Tail Method Vector Subtraction Multiplication of Vectors and Scalars Resolving a Vector into Components Summary Section Summary Overview of the Types of Forces Categories of Forces Summary of All Forces A First Example to Understand Tension More on Tension Viscous Forces[footnote]From Viscosity.

The Units and Some Values of Viscosity Why do different animals look different? What you need to figure out Additional data you may need What is involved in running? What you need to figure out When you eat a fatty food, the pleasure centers of your brain light up. How does your brain know? What you need to figure out How much force can a bacteria exert? What you need to figure out The Mean The Median The Mode Order Relationship of Measures of Center Calculating the Mean of Grouped Frequency Tables The Standard Deviation The Standard Deviation in Context Z-scores Identifying Unusual Values with the Standard Deviation Simplify Expressions by Combining Like Terms Solve Equations Using the Subtraction and Addition Properties of Equality Solve Equations That Need to Be Simplified Solve Equations Using the Division and Multiplication Properties of Equality Solve Equations That Need to be Simplified Solve an Equation with Constants on Both Sides Solve an Equation with Variables on Both Sides Solve Equations with Variables and Constants on Both Sides Solve Equations Using a General Strategy Attributions Use Variables and Algebraic Symbols Identify Expressions and Equations Simplify Expressions with Exponents Simplify Expressions Using the Order of Operations Key Concepts Glossary Practice Makes Perfect Answers Attributions Identify Terms, Coefficients, and Like Terms Evaluating Algebraic Expressions Solve Quadratic Equations Using the Quadratic Formula Use the Properties of Triangles Right Triangles Use the Pythagorean Theorem Summary Attributions Sine, Cosine, and Tangent Ratios Trigonometric Ratios Finding Missing Sides of a Right Triangle Finding Missing Angles of a Right Triangle Solving a Right Triangle Solve Applications Using Trigonometric Ratios Key Concepts Attributions Key Concepts and Summary Learning Objectives Key Concepts and Summary Glossary Line graphs What you can read off a graph Summarizing the Physics Rectangles Triangles Circles Surface Areas and Volumes Systems of Linear Equations: Two Variables Trigonometry
