Abstract An experiment was performed to measure the quickening collectable to graveness g. The quickening collectible to gravitational force was determine statically by touchstone how the quantify period of times of the oscillations of a give nonicedid pendulum error with the aloofness of the pendulum. The resulting entertain of g extracted in the experiment was 9.757m/s², which is just 0.5% less than the suppositious value, 9.81m/s². Introduction and divinatory Backg cps If sobriety is the only strike out acting on an physical object, then we find the object allow for accelerate at a rate of 9.81 m/s². This value is know as the acceleration of gravity and is denoted by the symbol, g. This constant appears in the relationship of the period of a unproblematic pendulum to its aloofness. By measuring how the time periods of the oscillations of a simple pendulum vary with the space of the pendulum a value for the acceleration due to gravity g force out be extracted. As discussed in file name character reference [1] the simple pendulum consists of a depressed bob of mass, m obviate by a inflame inextensible thread of length l from a pertinacious point. If the bob is drawn parenthesis slightly and released, it oscillates. The time period T (in seconds) for one round out oscillation of a simple pendulum is given by; T=2? ? l/g Where l is the length of the pendulum (in meters) and g is the acceleration due to gravity (in m/s²).
This par is only binding when the angles of oscillation are small, i.e. ? does not spend 10°. Squaring the equation for the period T gives, T2 = (4?2/ g) l A fairly stainless determination of g can be made by measuring T for unalike determine of l and plotting a graph T2 versus l (i.e. T2 on the y axis and l on the x axis). The solution should be a satisfying line which passes through the origin, with a slope (G) of (4?2)/g. The value of acceleration due to gravity g is then, g= 4?2/G From a measurement of the incline G of the graph it is contingent to extract a value for the acceleration due to gravity g.
