Simple Pendulum

LAB REPORT Factors affecting Time extremity on a unsophisticated Pendulum Introduction: Background: In  mechanics and physics,  unsophisticated harmonic transaction is a type of  triennial interrogative where the restoring big businessman is directly proportional to the transmutation. It smitten serve as a mathematical model of a variety of campaigns, much(prenominal) as the oscillation of a leap. In addition, former(a) phenomena can be approximated by simple harmonic motion, including the motion of a simple pendulum as well as  molecular vibration. Simple harmonic motion is typified by the motion of a potfules on a spring when it is subject to the unidimensional stretchy restoring force given by Hookes Law, or illustrated by the perennial movement of a simple pendulum. The motion is sinusoidal in term and demonstrates a single resonant frequency. This execution was initiatory noticed by Galileo in 1581. He watched the lamps in Pisas cathedral baseball swinging backwards and forwards. The time for each swing stayed almost the same even as the swinging died down. Galileo agnise that this regular pattern could be utilize for time keeping. thence when an object oscillates with constant time period even if the premium varies, we say it is moving with simple harmonic motion (SHM).

meditation: In any system where at that place is a restoring force (Hookes law: F = -kx) or a restoring tortuousness that tends to move the system back towards an rest position, the system give tend to oscillate. When the restoring force or torque is proportional to the displacement from equilibrium, given by: x = x max cos(?t) where ? is th e angular frequency. The angular frequency ! is related to the frequency, f, and the period, T, by the equation: ? = 2?f = 2? / T ii examples of systems experiencing simple harmonic motion are a mass on a spring, where the spring provides the restoring force that is proportional to the displacement, and a pendulum, where the restoring torque is provided by a component of the gravitational force. [Note: For a pendulum the restoring torque...If you want to get a full essay, order it on our website: OrderEssay.net
