After 3 weeks
Hi there!
So far so good. We are not able to complete Chapter 5 as scheduled but I guess we will catch up those topics next week. I know some of you are far ahead but I purposely went pretty slow so that others could grab the ideas and concepts firmly. You know, when talking about Newton's Laws of Motion, the most important elements are the mathematics behind them. You must be able to relate the mathematical concepts such as vectors into those laws. In high school, I believed the mathematical concepts were also discussed but perhaps very briefly. And now suddenly you are dealing with a lot of mathematics to solve most of the problems.
I'm thinking of giving you guys a quiz next week probably on Tuesday, August 4th. The topic will be on projectile motion and it will be conducted during our lecture periods. A week after that, on Tuesday August 11, I'm planning to give Test 1 which will cover Chapter 1 - 5. I'll discuss on this matter with you guys later.
Please keep posted and have a nice weekend!

Our week 2 ...
Hi guys!
Our week 2 went extremely fast. Hope all of you could follow and understand each and every topics very well. On my part, I had a rough time to control my coughing and it really bugged me. Alhamdulillah maybe there is blessing in disguise, perhaps it is a reminder to me to take care of my health seriously.
You guys were very active during our lectures and discussions, and almost everybody seemed to participate. Even the only "alien" among you was hyper. Just kidding! Nevertheless, there were one or two who looked very tired or did not pay much attention to our lessons. But overall, I'm extremely pleased with your attitude. Please keep up the momentum and if I'm not mistaken we are going to have our first test on September 18, 2009. I'll keep you guys updated.
OK guys, if you have any queries please keep me posted either through my e-mail or blog. Take care and looking forward for our next class, God willing.

Quiz #1
Hi Students.
It is time for our first quiz. Please answer the following questions on an A4 size paper and submit to me during the class hours on 21.07.09. Please include your name and ID number.
Have a nice weekends!
a) If the average velocity of an object is zero in some time interval, what is the displacement of the object for that interval? Please explain.
b) Two cars A and B are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does this mean that the acceleration of car A is greater than that of car B? Please explain.
c)A baseball is hit so that it travels straight upward after being struck by the bat. It takes about 3.0 s for the ball to reach its maximum height. Find:
i) The initial velocity of the ball after being hit.
ii) The maximum height reached by the ball.

Dearest students!
Our week 1 lessons went quite smoothly. Majority of you especially the ladies participated actively during the classes. But a few guys in the middle row for both sections chose to remain quiet. Perhaps that kind of learning style suits them well.
By the way, there are some hiccups which I hope we could rectify as the weeks go by. For section 1, the front row is too close to the white board and I have trouble to place my projector properly. And I think if I were to use an overhead projector for transparency, probably there is no space to accomodate it. As for section 2, the room is too glaring especially for the afternoon class. I think a curtain will do to minimize the glare.
In term of schedule, I think we are on the right track and all the planned lesson are completed as scheduled. Except for section 2 where we still have topic on "Free Falling Objects" to cover. Otherwise we are OK. Please take note that I'm planning to give the 1st quiz next week based on the topics that we have learned so far.
So long and see you guys in our next class, God Willing. Bye.
