Mastering Physics
Why do we do homework?
Homework is not for us…we know it already The only way to learn physics is by doing problems and thinking
about it
Doing problems helps test your understanding
Mastering physics used to allow a more careful check of your homework, so you know if you are doing it right.
It also has tutorial to try to help if you don’t understand. It is part of your grade because we think it is important that you do
the problems
Exam problems will be very similar to the assigned (and suggested problems look at homework sheet:

This will be your way to check your grade. Don’t wait until Dec 11 to check.
Grade scale A+ 98% A 93% A- 89%
B+ 85% B 78% B- 73% C+ 68% C 60% C- 55%
D 45%
This is the maximum grading scale…some parts might shift down (for example B to 75%) if necessary because of a test that turns out harder than we expected.
Above has links to two articles, one from the Herald and one in Science magazine.
We will be using iClickers this semester. We are using these because research in the Physics Education Research (PER) community has shown that they are a very effective tool to increase student learning and comprehension when used properly.
Part of using clickers will be to test class understanding of conceptual ideas, allow peer interaction, and give me feedback on what you do/do not understand.
Clicker questions will be part of your grade. Will average all of one days answers into a single day’s score.
In survey’s, when done right, 90%+ of the students enjoyed the process and over 77% thought they learned more because of them
IF A STUDENT IS FOUND WITH TWO REGISTERED CLICKERS IN CLASS, THE PENALTY IS THAT THEY WILL BE IMMEDIATELY FAILED FOR THE CLASS.
Registering Clickers
We will start clickers next Tuesday.
Register your clicker by going to www.iclicker.com Need to put in:
Your last name
First name (use the name that is on the rolls C#
Number from back of clicker
Sources of Help
ATTEND CLASS…someone is paying your tuition bill, take advantage of it.
1-2 Units of Length, Mass, and Time SI units of length (L), mass (M), time (T): Length: the meter Was: one ten-millionth of the distance from the North Pole to the equator Now: the distance traveled by light in a vacuum in 1/299,792,458 of a second Mass: the kilogram One kilogram is the mass of a particular platinum-iridium cylinder kept at the International Bureau of Weights and Standards, Sèvres, France. The one standard not tied to a physical phenomena Time: the second used to be a fraction of a day Now:One second is the time for radiation from a cesium-133 atom to complete 9,192,631,770 cycles.
This was hopefully the last lecture I will give For next week, before class Be prepared for: Tuesday Sections 2.1 – 2.4 Thursday Sections 2.4-2.6 There will probably be a quiz on this material to start class.
