Designing an Experiment 1. Aim: To investigate how the space of a pendulum drag affects the time it consumes to oscillate * Independent Variable :The aloofness of the pendulum wind alongs (10cm, 20cm, 30cm, 40cm, 50cm) * myrmecophilous Variables: The aloofness of time that takes for the pendulum to stop swinging (seconds) * Controlled Variables: Mass of pendulum, types of make used, the go of the string which it pass on be released (30 degrees) 2. Hypothesis: The length of time that takes for the pendulum to stop swinging will enlarge as the length of the pendulum string increases. This is due to the feature that the pendulum travels greater quad in oscillation when the string is longer. The course of instruction of the pendulum is like an bowing on the bottom of a flock and the piece of string as radius. Thus, according to the circle theorem; circumference=2 x ? x Radius. Accordingly, as the radius increases, the circumference, in th is case the curve will also increase. The increase of the length of the arc leads to the increase of distance travelled by the pendulum and therefore, more than(prenominal) than time is needs more consumed. 3.

Apparatus/ Materials * Pendulum * 5 string; 10cm, 20cm, 30cm, 40cm, 50cm * Timer (records up to the 2nd decimal) * Clamp stand (including clutches) * principle; 1m * Scissors * Protractor 4. Methods 1) stones throw out 10cm of string by maturation a ruler 2) double over step 1) by making 10cm, 20cm, 30cm, 40cm, 50cm with the same method 3) Attac h the pendulum and the string to the indem! nify stand 4) Measure the tip off (30 degrees) which will be the angle which the pendulum will be released from the secure (or clutch) 5) Fasten the pendulum with a clamp 6) As you release the pendulum, start measuring the time until the ordinal oscillation of the pendulum. 7) Repeat this process 4)~6) 3times to obtain a more accurate result 8) Repeat the process 3)~7) by development different lengths of string (10cm,...If you want to get a seeable essay, order it on our website: OrderCustomPaper.com
