slide 1Physics L 1Frank Sciulli Introductory Physics Courses Designed for Engineering and Science Students l Three different introductory sequences for people with differing preparations, interests, and goals u 1400 sequence: emphasizes basics, connections in the world, and college level physics problem solving u 1600 sequence: + more abstract and theoretical; approach more mathematical; order of topics slightly different u 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 l All courses incorporate calculus at early stage l You are now in Physics 1401(1) … if you are well prepared in Physics, you are probably in the wrong course

slide 2Physics L 1Frank Sciulli Science/Engineering Sequences SequencePoints Recommended Median Grade Separate Lab Course Physics B/B or 1494 Physics , and mid B or 2699 Physics 2801, B + /A

slide 3Physics L 1Frank Sciulli 1400 Sequence l Three semester sequence (no labs included) u 1401-Mechanics and Thermodynamics u 1402-Electricity/Magnetism and Optics u 1403-Wave motion and Quantum Mechanics l Each is worth 3.0 points l Recommended median grade at B-B + interface l Separate Lab courses (when appropriate) u If only, take 1493 in 3 rd semester u If all 3 semesters, take 1494 in 4 th semester l Emphasizes basics, connections in the world, and college level physics problem solving

slide 4Physics L 1Frank Sciulli Text and Topics l Text is Halliday, Resnick, Walker; "Fundamentals of Physics", 6th ed. (with metromedia CD) Chapters 1-15, u Mechanics: includes linear motion, forces, energy, rotations, thermodynamics l Note that chapters 16 – 18 are not covered this semester. u These include topics on harmonic motion, waves, … u These topics are part of the third semester (1403) in the sequence

slide 5Physics L 1Frank Sciulli Mechanics of this Course l No handouts u All information transmitted on the web! l Grades (I hate them, but …responsibility to be FAIR!) … detailed policy at website u you MUST be able to do problems in exams u 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. u College course: assume all are mature adults l Check out the home page and links – all information that I thought useful is written there … u sorry for the pun!

slide 6Physics L 1Frank Sciulli History (Big Picture)

slide 7Physics L 1Frank Sciulli Physics – Matter and Forces This course is meant to begin the study!! Physics 1401

slide 8Physics L 1Frank Sciulli Predictive Nature of Physics Useful l And deadly if neglected !!!!

slide 9Physics L 1Frank Sciulli History (people oriented)

slide 10Physics L 1Frank Sciulli Mathematics x=x 0 +vt Every formula carries a concept! Read them that way The math (algebra, trigonometry, calculus) are tools to ends!

slide 11Physics L 1Frank Sciulli Immediate Future l I assume you know (reviewed in text) u algebra and trigonometry well!! u vector familiarity (review elementals as we go.) u calculus simultaneously (know fundamentals!.) l All assignments and due dates are posted. See website. l Chapter 1 (Measurement, numbers,...) should be a review of what you know. Read it and make sure. l Chapters 2 (1D motion) and 3 (vectors) also should be largely review. l I will go quickly through first few chapters (so we have time to get through the topics programmed for the semester).

slide 12Physics L 1Frank Sciulli Simple problem (like sample 1 – 4) 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?  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.

slide 13Physics L 1Frank Sciulli Definitions of velocity and acceleration

slide 14Physics L 1Frank Sciulli Velocity l Average velocity u Interval dependent l Instantaneous velocity u Limit of interval = 0

slide 15Physics L 1Frank Sciulli In the Beginning l 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.) l Chapter 2: Position, velocity, acceleration in one- dimension (1D). Should also be largely a review. Some discussion here. Problems assigned. l Chapter 3: Vectors -- essential for discussion of more than 1D. We will discuss. l 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
