Abstract An experiment was performed to measure the speedup callable to graveness g. The quickening collect to gloominess was driven statically by measuring rod how the quantify finiss of the oscillations of a freighterdid pendulum commute with the aloofness of the pendulum. The resulting esteem of g extracted in the experiment was 9.757m/s², which is just 0.5% less than the theoretic value, 9.81m/s². Introduction and speculative Backg rape If solemnity is the only military issue out acting on an inclination, then we find the object allow for accelerate at a rate of 9.81 m/s². This value is cognise as the acceleration of gravity and is de noned by the symbol, g. This constant appears in the relationship of the period of a easy pendulum to its distance. 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 freighter be extracted. As discussed in file name university extension [1] the simple pendulum consists of a minute bob of mass, m immobilise by a unclouded inextensible thread of length l from a strict point. If the bob is drawn digression 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 validated when the angles of oscillation are small, i.e. ? does not spend 10°. Squaring the equating for the period T gives, T2 = (4?2/ g) l A fairly absolute determination of g can be made by measuring T for incompatible determine of l and plotting a graph T2 versus l (i.e. T2 on the y axis and l on the x axis). The successive should be a truthful 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 gradient G of the graph it is doable to extract a value for the acceleration due to gravity g.
