Introductory Mechanics
Latest news
 The final exam in the course has been set for Tuesday, April 16, 14:0017:00 in B209.
One sheet of formulas (onesided) may be brought in; it may not contain solutions to problems and it will be handed in with the exam.
Calculators (without alphanumeric memory or network connectivity) are allowed; no other aids.
 Midterm test: Mar 1 (Fri). Allowed: calculator and one selfprepared onesided lettersize formula sheet which may not contain solutions to problems; not allowed: textbooks, lecture notes, laptop or tablet computers.
 A brief note of introduction to basic data analysis and plotting tasks has been added
to Lectures. A static web page can be viewed
here,
but a better way is to save (rightclick on) this
jupyter notebook, open a terminal
window in the directory where you save it, run the command jupyter notebook, and
open the notebook this way.
 Lectures: T F 9:3011:00, in
TH240 B209, starting Friday, Jan. 25.
What Brock calendar entry says:
 Mechanics of particles and systems of particles by the Newtonian method; conservation of linear momentum, angular momentum and energy; elementary dynamics of rigid bodies; oscillators; motion under central forces; selected applications.
What do I need to bring into the course?
 This course is a core course of the Physics program, and requires Y1 Physics and Math courses as prerequisites.
Course Goals
 to further develop an understanding of Newton's laws of motion and their origin in and application to real physical systems
 to discover the underlying conservation laws governing the evolution of physical systems
 to gain experience in the use of advanced mathematical tools (e.g. advanced algebra and trigonometry, analytic geometry, differential and integral calculus, differential equations)
 to understand more comprehensively physical phenomena and the manner in which physical systems evolve with time.

 Lectures: T F 9:3011:00, in TH240. Labs: M 14:0017:00, B203. The labs begin next week:
 Jan 14: Introduction to computing I (overview of Physics workstations, CLI and bash programming)
 Jan 21: Introduction to computing II (physica/gnuplot/octave plotting/data analysis; LaTeX/overleaf)
 Jan 28: see the first lab in the lab manual
 Please, monitor the Homework link regularly.
 If you want to make use of xournal, look here, available for Linux and Wind**s.
 You are expected to prepare your lab reports using LaTeX. It is available on all computers in
Physics labs, and online at overleaf.com.
Some useful resources for writing lab reports are here.
See a sample report in LaTeX, a physica online link, a tutorial on writing physica macros, etc.
The same sample lab report is also available as
an overleaf template (clone as your own).
 Just in case you missed it: the preparation for the next lab is to:
 log on to overleaf (sign up using your Brock email) and create a New Project from a template for "Brock Physics 3PXX lab report" (or use the link below on this page);
 generate a script for your favourite graphics package (physica recommended) that includes both a directly entered set of data coordinates and a set of commands to generate a basic plot;
 use this script to generate a vector graphics output file (SVG or EPS recommended) and upload it to the subdirectory Figures in your project;
 make the obvious changes: name, title, references etc. to LaTeX code to make the template into your own lab report;
 record all questions that arise along the way and bring them with you on Monday.
