Report - Coursework ExampleThe use of a plain pendulum experiment in the study of motion helps to provide valuable insights into the acceleration of objects ascribable to the gravitation force. In this experiment, a rush is suspended from one end of a piece of string and set in motion to determine the number of oscillations in a particular period. Such an oscillatory motion (to and from motion) is referred to as simple harmonic motion. The time a pendulum takes to swing forth and back is affected by factors much(prenominal) as the pendulums length and the acceleration due to the gravitation. A shorter pendulum has a shorter period to complete a single oscillation than a longer pendulum. In view of this, this simple pendulum experiment used the congenator between the length applied in the pendulum and the time of oscillation to estimate the value of acceleration due to the gravitation force (Avison & Caribbean Examinations Council, 1988).The simple pendulum experiment was mainly conducted to facilitate the understanding of the relationship between divers(prenominal) parameters in an oscillatory system. In addition, the experiment seeks to use its data analysis to facilitate the calculation of a value for the gravitational acceleration (g) and compare this value with the widely accepted value of 9.81 m/s2.If a people of m hangs from the string in a simple pendulum experiment and sets to swing with small amplitude, the mass will oscillate back and forth in a simple harmonic motion. In this scenario, the mass of the bob becomes the inertia as the tangential component changes the direction e really time the bob (mass) passes the center field of its swing and hence acting to restore the mass to its midpoint. For this reason, the restoring force, F = - mg sin ().However, if the angle is very small, then it is assumed that sin () , hence, F = - mag.. Equation (1). The angle of displacement can be determined from the equilibrium using the arc length, x,
