1 Summary of Basic Probability. 2  In the following, the capital letters A, B, or C are used to represent some event like it will rain tomorrow or a computer chip is defective. The notation P(A) then stands for the probability of event A. 3  An experiment is any process yields a result or observation.
A pendulum is a string or stick with a weight or bob on the end. The pendulum follows the law of falling objects[ âan invisible force, gravity, pulls the pendulum toward Earth. The period of time it takes. a pendulum to complete one full swing is simply called the period. Three variables affect the period: the length of the pendulum, the. size of the arc it makes, and the mass of the bob. In this activity, youâll discover what happens if you change one or more of the. variables.
Investigating the Factors that Affect the Period of One Swing of a Pendulum. Aim: To investigate the factors which affect the period of one swing. (oscillation) of a simple pendulum. The factors I will use are length. of the string, and angle that the bob is released from. Hypothesis: 1. Length of string. I think that the length of the string directly affects the period of. one oscillation.
