Don't Do "Force times Displacement" on Sundays

Ahh, another lazy sunday. Again, I was sitting around, just staring at the wall visually what it would be like to have a TV in my room. Then EUREKA (again!), why not move my sister's tv in to my room. As I walked into her room, I stared down the massive TV. Why would I want to work on the weekend. FOOLISH! But the urge to watch tv in my room was just too great. I embarked on Operation: TV Displacement. Using my really, really, ridiculously huge muscles, I lifted the television, but as a sat there with the tv hoisted up, I realized I was in no position to move. Waiting there for what seemed like hours, the weight of the tv bared down on me and I applied an equal force upward to support the tv. I was sweating profusely, my arms shaking uncontrollable; how much longer could I take this. I was exerting a lot of force, and it felt as if i was doing a tremendous amount of work, but in fact, because there was no displacement, I did not do a single joule of work. After this epiphany I quickly put the TV down and realized my foolishness. I decided that instead of having to lift it and not do any work, why not drag it. Dragging it across the floor by the cord, I was doing work. The force I was exerting times cos of the angle of the cord to the ground multiplied by the displacement equaled the work. AHH, but FATAL ERROR! The darn ground had friction, causing me to exert an even greater force to overcome such friction. Perplexed once again, I asked myself WWDD (What would Doc do?). Clearly Doc! would be efficient and carry the tv. So I decided to DOC IT UP! By exerting the force in the same exact direction as the displacement and carrying it to not deal with friction from the floor, I would be doing as little work as possible, while still achieving the same objective. Thank goodness for the wise Doc!. Without this genius, I would've been working so hard on Sunday, and all good Christians know that we're not suppose to work on Sundays. Better yet, I should've followed Grandma's advice and let my dad do the work for me, because Grandma loves dad working, but hates Robert working. So remember: DOC IT UP!

The Elevator Ride (10x)

Sitting at home on a blissful Sunday, I suddenly realized something spectacular. EUREKA! Why spend time sitting on the couch, when i can go fight the traffic of Waikiki and ride the elevator to the the "Top of the I" where Sarentos is located. In no less than thirty minutes, I went from sitting at home, to having the exhilarating thrill of riding an elevator to the top of a hotel multiple times (10 to be exact). On the first ride, I merely closed my eyes and imagined the body diagram with the object in the shape of a sixteen year old boy. Going straight down, I pictured my weight (mg) and going directly opposite of that direction. Normal force! The earth was not pulling me down, but rather that tingling, irresistible sensation in my feet, was the normal force, pushing up at me. Keeping my eyes closed, I embarked on a second journey to the Top of the I. Trusting my hands out, I action-nized my body diagram. Showing that when the elevator goes from rest and starts moving to upward, there is a period of acceleration. During this period, the net force is going upwards, and since weight is the same, the normal force (that tingling sensation in my feet) was greater, making me feeling heavy. After that period, normal force became equal with weight because the acceleration of the elevator was constant. When I reached the top, the elevator had a period of deceleration, where the net force was still up wards, but in order to slow down, force normal had to be less than weight. After merely waving to the receptionist at the top, I embarked on the journey downwards. Acceleration occurred at the beginning of this journey, where net force was downward, causing normal force to be less than weight, making me feel weightless! AHH THE MADNESS! Just before reaching the lobby floor, the elevator decelerated, where force normal was greater than weight causing me to feel heavy again. All this new found knowledge made me want to express Grandma's and my joy for physics. Opening my eyes again, I realized that several tourist passed judgment on me and quickly left the elevator. I decided to ride the elevator 9 more times in search of a student. On the 10th try, the manager of Sarentos came inside the elevator. Throughout the entire 30 second elevator ride, I whizzed through a whole lesson on forces, weight, and normal force. After my explanation of that awesome feeling we had in our feet when in the elevator, the manager merely exclaimed, "Physics is cool...". Despite his lack of enthusiasm, I must say...Doc would've been proud. Ten times up and down the elevator not only took over thirty minutes, but also made me sick to my stomach. Not to mention the receptionist at the restaurant questioning me several times on why I kept reappearing every 2 minutes. I suddenly realized why Grandma hates Elevators and Sarentos; it's because the ride is just far too long! Grandma prefers the ground far more than the top of hotels.

The Beginning

Periods 1 and 2 are fun-filled minutes in a class called Physics. Over the first couple weeks I have transitioned from the lazy summer days to homework and the daily schedule of school. At first, I was intimated by the letters AP in front of the course name. I did not know what to expect. I was nervous about the course load and the increased responsibility such a course put on me. Now, I can't wait too see what we will learn throughout the year. I am excited and extremely curious about what lies ahead. It saddened me to hear that Grandma doesn't love Robert, but since Grandma loves Physics, then there has to be a ton of fun things ahead. Just like Spongebob, "I'm Ready!" to have some fun!
