Introductory Physics Courses Designed for Engineering and Science Students Three different introductory sequences for people with differing preparations, interests, and goals 1400 sequence: emphasizes basics, connections in the world, and college level physics problem solving 1600 sequence: + more abstract and theoretical; approach more mathematical; order of topics slightly different 2800 sequence: the three semesters of the 1600 sequence in two semesters; specifically for students with advanced placement in mathematics and strong background in physics All courses incorporate calculus at early stage You are now in Physics 1401(1) … if you are well prepared in Physics, you are probably in the wrong course Physics 1401 - L 1 Frank Sciulli slide 1 Science/Engineering Sequences Recommended Separate Median Grade Lab Course Sequence Points Physics 1401-2-3 3.0 B/B+ 1493 or 1494 Physics 1601-2, and 2601 3.5 mid B+ 1493 or 2699 Physics 2801, 2802 4.5 B+/A- 3081 Physics 1401 - L 1 Frank Sciulli slide 2 1400 Sequence Three semester sequence (no labs included) 1401-Mechanics and Thermodynamics 1402-Electricity/Magnetism and Optics 1403-Wave motion and Quantum Mechanics Each is worth 3.0 points Recommended median grade at B-B+ interface Separate Lab courses (when appropriate) If 1401-02 only, take 1493 in 3rd semester If all 3 semesters, take 1494 in 4th semester Emphasizes basics, connections in the world, and college level physics problem solving Physics 1401 - L 1 Frank Sciulli slide 3 Text and Topics Text is Halliday, Resnick, Walker; "Fundamentals of Physics", 6th ed. (with metromedia CD) Chapters 1-15, 19-21 Mechanics: includes linear motion, forces, energy, rotations, thermodynamics Note that chapters 16 – 18 are not covered this semester. These include topics on harmonic motion, waves, … These topics are part of the third semester (1403) in the sequence Physics 1401 - L 1 Frank Sciulli slide 4 Mechanics of this Course sorry for the pun! No handouts Grades (I hate them, but …responsibility to be FAIR!) … detailed policy at website All information transmitted on the web! you MUST be able to do problems in exams homework, though only a small component of the final grade in itself, is an ESSENTIAL tool to assure yourself you know the concepts and how to do problems. College course: assume all are mature adults Check out the home page and links – all information that I thought useful is written there … http://www.nevis.columbia.edu/~sciulli/Physics1401/Ph1401.html Physics 1401 - L 1 Frank Sciulli slide 5 History (Big Picture) Physics 1401 - L 1 Frank Sciulli slide 6 Physics – Matter and Forces Physics 1401 This course is meant to begin the study!! Physics 1401 - L 1 Frank Sciulli slide 7 Predictive Nature of Physics Useful And deadly if neglected !!!! Physics 1401 - L 1 Frank Sciulli slide 8 History (people oriented) 13 109 BCE Universe started 5 109 BCE Solar system & Earth formed 2 -1 106 BCE Man precursors with small brains 105 BCE Homo Sapiens with BIG brains 104 BCE Writing (for business) 1000 BCE Bible written down 400 BCE -400 Greeks, Romans … ideas … many wrong 1400-1650 DaVinci, Brahe, Copernicus, Galileo 1650-1900 Newton, … -- Classical Mechanics 1750-1900 Franklin,…Maxwell --Electricity&Mag 1900- "Modern" Physics Physics 1401 - L 1 Frank Sciulli slide 9 Mathematics x=x0+vt Every formula carries a concept! Read them that way The math (algebra, trigonometry, calculus) are tools to ends! Physics 1401 - L 1 Frank Sciulli slide 10 Immediate Future I assume you know (reviewed in text) algebra and trigonometry well!! vector familiarity (review elementals as we go.) calculus simultaneously (know fundamentals!.) All assignments and due dates are posted. See website. Chapter 1 (Measurement, numbers, ...) should be a review of what you know. Read it and make sure. Chapters 2 (1D motion) and 3 (vectors) also should be largely review. I will go quickly through first few chapters (so we have time to get through the topics programmed for the semester). Physics 1401 - L 1 Frank Sciulli slide 11 Simple problem (like sample 1 – 4) Eratosthenes (300 BCE) measured radius of the Earth to 5% using geometry, angle between Aswan and Alexandria. See NY Times, Sept 24,2002 Science’s 10 most beautiful expts. Earth spherical? Measure radius! 1. Mark lake level at location of ship and place meter stick on ship side 2. Go to lake shore (d = 4.4km) and sight along lake; find that sighting is on ship side at h = 2.0m. 3. What is the radius, R, of the earth? Physics 1401 - L 1 Frank Sciulli slide 12 Definitions of velocity and acceleration Average velocity x v t Average acceleration v a t Physics 1401 - L 1 Frank Sciulli slide 13 Velocity Average velocity Interval Instantaneous velocity Limit v avg dependent of interval = 0 x v t 6m Case shown v 2 m /s 3s v inst Physics 1401 - L 1 x dx v lim t 0 t dt Frank Sciulli slide 14 In the Beginning Chapter 1: Units, Dimensions, powers of ten, idea of mass. Should be mostly a review. Make sure you can do the problems in the text. (None assigned.) Chapter 2: Position, velocity, acceleration in onedimension (1D). Should also be largely a review. Some discussion here. Problems assigned. Chapter 3: Vectors -- essential for discussion of more than 1D. We will discuss. Next lecture, review chapters 2 & 3. Read them and start on assigned homework problems soon. Finish the day with a pretty description of the scales of physics … Phillip Morrison Physics 1401 - L 1 Frank Sciulli slide 15
