This year I was very busy during the fair. However not busy with work, but busy with buying Vuvuzellas!. I somehow got three vuvuzellas at the fair this year. While most of the people play one long and somewhat annoying note on the vuvu, I learned how to create different frequencies and notes, by changing the length of the vuvu. As you shorten the vuvu the pitch goes up, and as you extend the vuvu the pitch drops. This change in frequency and pitch allow you to create different notes and simple songs.
Tiny wings is a very addicting game. The object is to assist ur tiny bird, with “tiny wings”, in soaring over hill and dale. The to obtain a high score you must fly from island to island, wit each island increasing in difficulty. The first island has low amplitude waves, with even wavelengths making it easy to judge the timing for descent. If you timing is perfect and ur bird gracefully caresses the downward slope of the wave you get bonus points and a nice extra boost. As you move from island to island the amplitude and frequency of the waves increase making it harder to get “perfect jumps”.
I have always wondered how my home in mililani gets it electricity. There are no tall electric poles, and no loud buzzing sounds. But after physics and a long walk with my dog kea I found the answer. A transformer!!! Hidding in the bushes. This transformer takes te high voltage and decrease it into bite size portions that can be used in homes
The fluorescent lights have a gas discharge that uses electricity to excite mercury vapor. They can produce electrical power into visible light more efficiently than incandescent light bulbs. There is amazing physics at work every time you turn on a light.
The other week it was my dad’s birthday, and we wanted to hang birthday balloons in the house for decoration, but we had no tape!! So we had to run to the store and buy some tape, just to hang the balloons. But now that I have learned good physics and understand the concept of static electricity and charge, I will never have to run to the store for tape again. All i have to do is rub the balloon on my head, giving it a charge, and touch it to the wall. The balloon will be attracted to the wall and stay suspended. Also i will never have to worry about the words I wrote on the balloon not showing. If i write on the balloon and apply a charge to the opposite side, the words on the balloon will always be facing out. This is because even if you try to flip the balloon over it will flip back to the charged side. After the party is done all you have to do is grab the balloon, grounding it, and then it wont stick to the wall anymore. Thanks physics for saving me lots of time and money!
Whenever I am doing home repairs, or building something in 3D physics is all around me. Every screw I tighten, or nail or pound can be explained through physics. Whenever you pound a nail you can feel the different amounts of force created by holding the handle far away or close to the head of the hammer. This power couldnt be explained before, until now. This force is torque. Torque is found by multiplying the lever arm squared times the mass of the object. Therefore when you hold the hammer farther down the handle away from the head you create more torque and more force.
With basketball season right around the corner it is important to practice. I shoot around for hours trying to perfect my free throws. However now that I have physics, all I need to do is apply the right speed, velocity, and trajectory, and the ball will fall right through the hoop every time. Once the ball leaves my hand it becomes a projectile flying the the air. SWISH
The ball travels with forward and vertical motion. If it the basket didn’t interfere with the ball’s path, it would rise then fall for equal amounts of time. With a constant acceleration of -9.8 meters per second squared. With Physics I will never miss a free throw again. Thanks physics!
Everyday I wake up at 5:20, shower, and begin my drive to school. The 22.7 mile drive is always relaxing. If I drive at a constant speed of 60 mph, I will arrive at school in approximately 45 minutes. However with traffic the drive usually takes over an hour. In one day if I drive to school and back home, my total distance is 45.7 miles. But my total displacement is zero miles.
Displacement is the distance between point A and point B, your initial and final destination. Therefore if I drive to school and then take the same path home, my displacement is zero. If I make it to school in 45 minutes, driving at a constant 60 miles an hour, my velocity will be approximately 1 mile per minute. Velocity is the displacement over time.
