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.
n. 1. A body suspended from a fixed support so that it swings freely back and forth under the influence of gravity, commonly used to regulate various devices, especially clocks. Also called simple pendulum. 2.. (General Physics) a body mounted so that it can swing freely under the influence of gravity. It is either a bob hung on a light thread (simple pendulum) or a more complex structure (compound pendulum). 2. (Horology) such a device used to regulate a clockwork mechanism.
