Well today we viewed a couple more presentations!
We had a dose of the Mars Mission from Oliver...
and a presentation on telescopes from Sergio.
After we moved on to a couple of the sheets that Kizoriz handed out.
Well that pretty much sums it up.
Have a good weekend.
The next scribe will be...
Mr SiwWy
PS. Afternoon class worked on the Charges, Voltage, Energy lab from the green book.
Make sure you read the notes on potential, potential energy, potential difference.
Note the difference among them (pardon the pun :))

Hello everybody!
Today was the day we learned about energy! But before that we just went over a bunch of problems relating to work. Just gotta remember:
Work = Force * Distance
Work = Force * Cos theta * distance
(the Cosine theta find the component of the force that lines up with the distance)
Then we moved onto the video lesson, which summed up kinda goes like this:
- Review of Ft = momentum
- Then we learned that Fd = Energy or work = energy
- Energy comes in many many many forms electricity and light to name a couple
- From there it moved onto Kinetic and Potential energy
-Kinetic energy is the energy of motion
-Potential energy is stored energy
-They are related, when potential energy is transformed into motional energy the total energy stays the same by the law of conservation, so if 5J of PE is transformed into Kinetic energy there will still be 5J of energy in the system (assuming that which is transferred to the surroundings is negligible)
-Then with a brilliant demonstration on pulleys he showed us how each rope takes some tension force but the person would still have to exert the same amount of energy to move the object because they would have to pull a larger distance.
That pretty much sums up the class...

Hello everyone,
Today we started off by doing questions that we were assigned a while back. Kasia and Craig took the reigns there...
After that Mrs.K showed us how vectors work on angled planes. Basically you just have to separate gravity into parallel and perpendicular forces and your good...
Then we were assigned a quick review read from our texts and then a quicker section on angled planes...
We have to finish a sheet that was handed out and that other assignment for tomorrow...
The next scribe will be RENAN!
Have a good night,
