Task: To find out if the length of the string or the mass that it carries affects the movement and the speed of which it swings. Variables: The weight, length of string, wind (caused by air conditioners), how much the string is twisted, friction between thread and clamp. Invariables: Clamp, string, measuring equipment, stopwatch, person who does all the measuring and timing, weights, position where knot is tied, angle where it is released (amplitude). Prediction: We predict that as the mass that the string carries increase, the speed that the sting swings will also increase. We think that this is because as there is more weight pulling it downwards as it gets higher. Also, we predict that as the length of the string decreases, the swing speed will increase as the string is shorter. We think that this is because as the string is shortened, it is closer to...
