Hello,
This is where you come to find the links to the assignments for the school days. This document will be updated throughout the year, but should help keep you on track, especially if you compete in track (or any other sport).

As you will be writing a lab report at some point, here are the expectations and scoring system used by all the science classes at some point
For Those who need it math style on the Physics stuff.
A set of practice problems are below.
- Fundamental Principle – one set of laws
- 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.
- vave= d/t = or if you like Δd/ Δt
- vave=(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 =
- 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.
- 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
- Pressure and Forces in Fluids
- Pressure = force / area
- Recall the can with boiling water in it. Why does the can collapse when it hits to cold water?
- What is Bernoulli’s principle and what does it have to do with why a plane flies?
- Why does a perfume bottle spray, or the household cleaner come out of the bottle?
- What is Archimedes Principle?
- Can something float under water?
- Why do you seem to weigh less in swimming pool than on dry land?
- What is density?
- Pressure = force / area
- Work Power and Machines
- What is work?
- Force applied for a distance/displacement (yes there is positive and negative work, and you can undo the work you have done)
- What is work?
- What is power?
- Power = work/time
- So two things can do the same amount of work, but take different amounts of time. The less the time, the more powerful the machine is considered.
- Power = work/time
- What is a simple machine?
- Incline plane or ramp
- How does a ramp help you raise an object?
- Wedges and Screws
- How the related to an incline plane?
- How does a wedge assist in splitting a log?
- How do you calculate the mechanical advantage of a screw?
- Levers
- First Class
- Second Class
- Third Class
- What are the differences? Can you name the books examples or other obvious examples?
- What is the lever arm?
- Wheel and Axle
- How do you calculate the advantage?
- Pulleys
- How do you calculate the advantage?
- Incline plane or ramp
- Efficiency
- How do you calculate?
- Mechanical Advantage
- How do you calculate?
A set of practice problems are below.
