Welcome to the Father of the Sciences, or applied mathematics.
There will be sub-pages for specific topics and don't forget to check out the basic skills section for items that go to every science class. Saves me repeating if I put them in one place. The impacts on the ecology are also on its own page for the same reason.
TEST WEDNESDAY 28th or THURSDAY 29th
Watch the review videos there are two of them.
Part 1 of the test Review on Kinematics in 1d

NO BOOK COVER no NOTES on Test.
You will need to show me your notes on the review for the test too.
For the Final
Physics Fall Semester Final
You may have a index card which I will provide.
Fundamental Principle – one set of laws. Imagine trying to play a game of Clue where everyone at the board had different rules, yikes!
Avoid logical traps such as illustrated by Ancient Aliens – false dilemma.
Math is useful in science, in that it tells us how much, and establishes the usefulness of a model.
A model being something as simple as d = Vave * time to tell you how far something has traveled assuming your V and t are correct.
Basic Kinematic equations.
v(ave)= d/t = or if you like Δd/ Δt v(ave)=(vf+vi)/2
vf=vi+at
df = di + vit + ½ at2
vf2 = vi2 +2ad
Δv = vf-vi
Δt = tf-ti
Δd = df-di
a = Δv / Δt = which is vf=vi+at rewritten or is it the definition rewritten?
You are on the hook for drawing and using the vector triangle
R^2=x^2+y^2, x= R cosΘ, y=R sinΘ, Θ = arctan (y/x).
Therefore, there will be a 2d Motion/force/momentum problem possibly more.
Newton’s 3 laws
Why seat belts, or why is it the X direction velocity on projectile motion problems unchanging? Is an example of 1st law
Ft=mv version could ask how much time does something take, or what is the acceleration etc… for 2nd law problems.
Third law is very much tied up in the friction and forces triangle, for the force normal.
You are on the hook for drawing and using the friction and forces triangle
Fw = mg
Fn=-Fw cosΘ
Fapp = Fw sinΘ,
if just pulling the applied
or if exactly offset as demonstrated by constant velocity
Ff = Fn (µ) = µ (-mg) cosΘ
Momentum Perfectly Elastic Collision (the perfect bouncing) is where zero energy is lost due to deformation, sound and heat from the impact, therefore:
momentum initial equals momentum final
Two body problem is m1v1 +m2v2 = m1v1’ = m2v2’
Perfectly In-Elastic Collision (the perfect hit and stick) is where zero energy is lost due to deformation, sound and heat from the impact, therefore: momentum initial equals momentum final
Two body problem is m1v1 +m2v2 = mfinalv1final
A combination of a super all in one sort of problem, or materials from homework problems are on deck for the final exam. Below is a file from the text books test generator or traditional types of problems. I will create a Rube Goldberg type problems for you to practice with too. Then we can discuss which one works best for you to demonstrate your knowledge.
