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.
(That is, one complete oscillation takes exactly 14 s .). 2. After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 47.0cm. The explorer finds that the pendulum completes 91.0 full swing cycles in a time of 127s.fter landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 47.0cm.
