    first mechanical clock was invented in the early 1300’s. With this invention time began to be measured in hours (24 hours equaling a day). Galileo‚ an Italian scientist‚ discovered the pendulum in 1581. The pendulum greatly improved the constant movement of the hands or bell of a clock. The average error with the pendulum varied only by seconds each day. Before this the error was from 10 to 15 minutes a day. During the 1600’s the metallic gear‚ or toothed wheel‚ and the use of the screw in assembling

    When Everything Changes- Change Everything? How do you deal with change? Are you a change-agent or a mere resistance to change? Are you intimidated with the possibility‚ and have the pessimistic ‘what-if’ personality? Do you change the change itself by physical or clout power? Or are you strong and welcome the possibility of something new? How do you take change? How should you take change? I guess I just flustered you with my mountain of enigmas. Sorry! I would still like you to answer those

    indirect measurement. Direct measurement is used to calculate the mass and volume of object eg. magnet bar‚ pendulum bob and marble by using vernier calipers. By finding the density‚ we could determine the specific gravity of the object(the ratio of its density versus that of water‚ ρwater=1000kg/m3). ρ=m/█(v@ ) Apparatus: Newton gauge‚ metal samples which are magnet bar‚ marble‚ pendulum bob‚ small nut and big nut‚ beaker‚ and graduated cylinder. Procedure: The weight of one of the metal

    Acceleration Due to Gravity with a Simple Pendulum Quintin T. Nethercott and M. Evelynn Walton Department of Physics‚ University of Utah‚ Salt Lake City‚ 84112‚ UT‚ USA (Dated: March 6‚ 2013) Using a simple pendulum the acceleration due to gravity in Salt Lake City‚ Utah‚ USA was found to be (9.8 +/- .1) m/s2 . The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported by the data

    good stories‚ there is always a dilemma‚ and with the struggle of that problem comes fear‚ but what truly shows that character’s mental strength or personality is how they handle that problem. In the stories‚ ¨The Tell-Tale Heart‚” ¨The Pit and the Pendulum‚”and ¨The Masque of the Red Death‚” all of the main characters experience fear‚ but handle it in very different ways. Whether they use that fear to help them overcome the problem‚ or their fear results in paranoia. Edgar Allan Poe uses symbolism

    Example: Modeling a Bus Suspension System using Transfer Function Zidarta - jimfackyou@hotmail.com Physical setup Photo courtesy: Eisenhower Center Designing an automatic suspension system for a bus turns out to be an interesting control problem. When the suspension system is designed‚ a 1/4 bus model (one of the four wheels) is used to simplify the problem to a one dimensional spring-damper system. A diagram of this system is shown below: Where: * body mass (m1) = 2500 kg‚ * suspension mass

    Clock is the best invention in the world! The history of clocks is very long. There are many different types of clocks over the years. The word ‘clock’ was first used in the 14th century. It comes from the word for bell in Latin (“clocca”). The very first timekeepers were natural clocks such as the sun‚ moon and stars. Ancient people used sticks and stones to find out the time around 3500 B.C. When it was between 3500 BCE and 1949‚ the inventors improved clocks‚ and became the clock that

    whenever objects vibrate or oscillation. Periodic Motion * A repeated motion that occurs back and forth over the same path at regular intervals. Examples: * A Child on a swing * A wrecking ball swaying to and fro * A swinging pendulum of a grandfather clock Simple Harmonic Motion (SHM) * Is a type of motion along a straight path in which the acceleration is proportional to the displacement of the object from its equilibrium position and is always directed toward the equilibrium
