Simple Pendulum Revisited
We describe a 8085 microprocessor interface developed to make reliable time period measurements. The time period of each oscillation of a simple pendulum was measured using this interface. The variation of the time period with increasing oscillation was studied for the simple harmonic motion (SHM) and for large angle initial displacements (non-SHM). The results underlines the importance of the ...
متن کاملThe (Not So) Simple Pendulum
Pendulums are the defining feature of pendulum clocks, of course, but today they don’t elicit much thought. Most modern “pendulum” clocks simply drive the pendulum to provide a historical look, but a great deal of ingenuity originally went into their design in order to produce highly accurate clocks. This essay explores horologic design efforts that were so important at one time—not gearwork, w...
متن کاملKapitza Pendulum: A Physically Transparent Simple Explanation
The phenomenon of dynamic stabilization of the inverted pendulum whose pivot is forced to oscillate with a high frequency in vertical direction is revisited. A simple physically meaningful explanation of the phenomenon is presented, followed by the derivation of an approximate quantitative criterion of stability. A computer program simulating the physical system is developed, which aids the ana...
متن کاملSimple pendulum determination of the gravitational constant.
We determined the Newtonian constant of gravitation G by interferometrically measuring the change in spacing between two free-hanging pendulum masses caused by the gravitational field from large tungsten source masses. We find a value for G of (6.672 34±0.000 14)×10(-11) m3 kg(-1) s(-2). This value is in good agreement with the 1986 Committee on Data for Science and Technology (CODATA) value...
متن کاملSimple Linearizations of the Simple Pendulum for Any Amplitude∗
Two simple, interpolatory-like linearizations are shown for the simple pendulum which can be used for any initial amplitude.
