Simple pendulum experiment Essay Example for Free

Simple pendulum experiment try onA string mea certaind to be over 1 meter, so as when its continuance was macrocosm adjusted there was enough string to pull on from between the wooden blocks, was tied to a bob. The end of the string was accordingly placed between two wooden blocks and adjusted so that the length of the pendulum was 1 meter. The wood blocks were then placed in the clamp and the grip was tightened. The pendulum suspension was made sure to be friction-free so that the wood blocks could provide a point of suspension for the string. The angle at which the pendulum is skeletal out to should be small. The smaller the angle, the closer the harmonic motion it will behave because the restoring force is playing tangent to the arc the pendulum moves through instead of being outside of it. The time taken for 20 oscillations with the length of the pendulum being 1 meter was recorded but was also repeated for accuracy. The two times were averaged and the proceeds was d ivided by 20 so as to find the time for one oscillation which was then squared.The length of the pendulum was decreased by 0. 1 m each time. The pendulum should swing freely without hitting anything. A table was drawn to record the results and from this a graph was plot. Results Table showing the time taken for 20 oscillations for each length. Time for 20 oscillations l/m t1/s t2/s AverageGradient = g g= gradient g = 0. 24ms-2 39. 48 = 9. 79 ms-2 Conclusion Using a simple pendulum, the acceleration due to staidness was concluded to be 9. 79 ms-2.
