Monday, May 30th/2011 Magnetism and Electromagnetism

Today in class we have read pages 20-23 on Electromagnetism. We learned that an electric current can create a magnetic force that would be perpendicular to the electric current. We learned that the strength of a magnetic field is proportional to the current when the wire is straight. We learned how to find the direction of the magnetic field on a straight wire, when given the currents direction, by using the first right-hand rule. We also learned how to work with wires that are wrapped in loops (solenoid), by using the second right-hand rule. We were given
electromagnetism assignments to finish and tomorrow we will work on the physics lab worksheet we have, in class!
The next scribe will be Ahmed!

April 4th/2011 Physics

For class today we received 9 pages of notes and 3 pages of homework. We learned what standing waves, nodes (nodal point) and antinodes (loops) are. We also learned what a resonant frequency (natural frequency), fundamental frequency, harmonics, and overtones are. We got a good amount of notes that we should review before next class and we have to answer the standing wave questions #1-4 and harmonic questions #1-5 by next class. The next blogger will be Ahmed Rage for the next class.

Friday, March 4th 2011

Last Friday, in the beginning of our physics class, we received our movie assignment back (the one called Newton's 1st Law by Paul Hewitt, where we had to write down seven physics facts that we liked.). Then we went over the free body diagrams in our book, we finished the questions on page 41 and 42 (note: Static means not moving, and if a ball is on an incline slope the normal force exerted from the surface the ball is on, would be perpindicular to the incline). Then we finished up the lab, and it may be handed in by next Monday. Keep up the good work!

The next scribe for next class would be the one and only ahmed rage!
