Acadec Hike!

Hi! So we're having our first Acadec Hike!

A good chance for exercise, bonding, and speaking!

To bring:

Your prepared speech! It needs to written!

Water

Snack?

We meet up early in the morning of WEDNESDAY, December 28th 2011!

Music Studies

List your favorite songs, and we'll analyze them!

Meetings will now go until 5:00.

For those who need the bus, you guys are fine to go.

On certain days I am able to provide rides!

One more week (:

How to presentate for Acadec

1. Read and understand assigned pages in Resource
2. Think of interesting lesson plan, OR a lesson plan that would best convey info to decathletes
3. Look at and do Focus Quiz for your particular section, and ASSIGN it as homework!!
4. Have Fun
5. If you have it typed up, send it to me so I can post it on blogspot.

What we learned today, a bunch of magnetic formulas. Thank You Sharon! (:

F = qvB

F = force

q = quantity of charge

v = velocity

B = magnetic field

ϕ = BA cos θ

ϕ = magnetic flux

B =magnetic field

A = Area

θ = angle between velocity and magnetic field vectors

B = (µI) / (2πR) or = (MI) / (2πR)

B = magnitude of magnetic field

I = current travelling through a wire

R = distance from wire

µ or M = constant = 1.26 ´10-6

E = (Dϕ ) / (Dt)

ϕ = magnetic flux

t = time

New Stuff.

So I've added new authors to the blogspot:

• Diana Tran and Kristy Duong. (Anyone is really allowed to post, for legitimate reasons. Work is done on pretty much a volunteer basis.)
• I need someone to be test printer, someone who just goes to the copy room and prints stuff. Let me know if you want to help!
• I really like this (:

Notes for Today:

Momentum and Work

Momentum is the anything associated with collisions. COLLISIONS. COLLISIONS. COLLISIONS. means MOMENTUM.

p = mv momentum = mass*velocity in the units of kg*m/s.

You can apply this in everyday life. Something with large mass, and low velocity has high momentum. E.g. You should be afraid of a slow charging elephant, because of MOMENTUM.

Likewise, something with small mass and high velocity has high momentum. E.g. Be afraid of a fast bullet, because of MOMENTUM.

MOMENTUM is always conserved.

Impulse = change in momentum

Dp = Ft impulse = Force · DTime

Take a air hockey puck for example, if you transfer the momentum for a long time, you won't have to hit it as hard. Basically, the change in momentum is affected by force and time. Let's take seatbelts. Seatbelts increase the time for you to hit the windshield so that the force isn't as great.

Elastic collision

Inelastic collisions.

Basically what we did today, Study.
