 Assignment 5 has been posted, due 20241121.
 Assignment 4 has been posted, due 20241107.
 Final exam: Dec 17, 9:0012:00, in the gym.
These are previously made announcements:
 Welcome to the home page of PHYS 2P20. Watch this space for important announcements.
 Lectures: Mo Th 10:3012:00, TH259, starting Sept.5.
 This course uses Brightspace primarily
to accept your completed homework and lab reports. For uptodate information, announcements,
and course materials, monitor this webpage.
 You are expected to prepare your homework and reports using LaTeX. It is available on all computers in
Physics labs, and online at overleaf.com.
In preparation, students are encouraged to open overleaf accounts. Some useful resources for writing reports are here, and will be reviewed in class.
 Labs: Mo(L1) Tu(L2) We(L3) 14:0017:00, in B203, starting Monday, Sept.9.
The first lab session(s) will include an introduction to computer use in the context of a Physics lab course. We'll cover basic interactions with the Linux operating system, file and data management and sharing on the Physics cluster, eXtrema and other plotting/data analysis packages, and writing lab reports using LaTeX.
The introduction to eXtrema will make use of the exercises of Experiment 1 from the lab manual.

 Reading week: October 1418, 2024.
 Assignment 3 has been posted, due 20241021.
 Midterm is on Monday, October 21, in class.
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 develop a more comprehensive understanding of Newton's laws of motion and their origin in and application to real physical systems;
 to discover the underlying conservation laws and the manner in which physical systems evolve with time;
 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 develop experimental data analysis, error estimation, and numerical modelling skills;
 to enhance scientific writing skills.
