Quiz on this maternal is NEXT CLASS: Friday Sept 7
Basic introduction to a crucial bit of mathematics: Right Triangle Trigonometry.
Quiz on this maternal is NEXT CLASS: Friday Sept 7
2: Mon Sept 12:
QUIZ 1!
Today we discussed standard and component form of vectors. We then did an activity to demonstrate the basic technique of vector addition using components.
3: Wed Sept 14:
More vectors.
Today we put the last two classes together. Trigonometry allows us to find the components of any vector. Then we can add any number of vectors using the component method from last class.
QUIZ 2 next class: Adding Vectors.
4: Friday Sept 16:
Vector subtraction. If you can add, you can subtract.
Basic idea is that
A  B = C
can be rewritten as
A + (B) = C
This is true for vectors, just as it is for scalars.
So to subtract, we simply add the opposite.
5: Tuesday Sept 20:
Introduction to the concept of the dimension of a quantity. Rules for addition, subtraction, multiplication, division and equality for dimension.
Discussion of units in calculation with a focus on unit conversions.
Notes on scientific notation and the metric system were handed out. We will not be dedicating any class time to this as it is considered prior knowledge.
6: Thursday Sept 22:
Discussion on concepts of accuracy and precision in measurement and significant figures.
Notes were handed out.
7: Tuesday Sept 27: TODAY WE BEGIN PHYSICS (UNIT 1)
Today we begin kinematics with a basic discussion of concepts that are a review of Science 9 and Science 10. This includes position, displacement, average speed, instantaneous speed, average velocity, instantaneous velocity and acceleration.
8: Thurs Sept 29:
Tougher example that required some real thinking. Introduce the idea of problem solving.
" A sprinter runs the 100.0m dash in 10.0s. The sprinter starts from rest and they accelerate (constant) for the first 3.0s. For the remainder of the race they run at top speed.
Find the acceleration and the top speed"
Visualise, diagram, list knows, "chunk" the problem, find links...

TEST ON IMPULSE MOMENTUM NEXT CLASS!
33: Thursday Dec 15
IMPULSE MOMENTUM TEST
34: Tuesday Jan 3
This is a challenging concept at first. Negative potential energy. The idea is that if two massive objects are infinitely far apart they will have ZERO POTENTIAL ENERGY; they apply no force to one another, thus at infinite separation they have no potential to gain kinetic energy based on their relative position. OK. But as two massive objects (think of a bowling ball and the Earth) get closer together (the bowling ball is lowered toward the surface of Earth) the potential energy DECREASES. So... the objects have ZERO potential energy when infinitely far apart, as they move closer together the energy DECREASES. What kind of numbers are less than zero?
35. Thursday Jan 5
