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.
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.he period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a small extent on the maximum angle that the pendulum swings away from vertical, Î¸0, called the amplitude.
