Physics 201 (General Physics-1) LAB #10 Simple Pendulum and Variables: Study of Scientific Method Your name: Olivia Beall Student ID: 7966485 Date: 7/12/2022 Lab partners name: Lab Instructor’s name: _____ Aiden Pereira ________ Prof. Stephen Kamanda _____ Mohammad Nawal ________ Objectives: The objective of this experiment was to investigate what variables influence the period of a simple pendulum. Theory: A simple pendulum may be described ideally as a point mass suspended by a massless string from some point about which it is allowed to swing back and forth in a place. A simple pendulum can be approximated by a small metal sphere that has a small radius and a large mass when compared relatively to the length and mass of the light string from which it is suspended. If a pendulum is set in motion so that it swings back and forth, its motion will be periodic. When we speak of the motion of the simple pendulum, we refer to the oscillations it performs, when the bob is taken to a height (the string remaining taut) and released. Materials and Methods: A mass was placed on a string and attached to a ring stand. A protractor was used to measure the angle at which the string was initially held, and it was then released. A stopwatch was used to record the time of 10 oscillations, and thus the period was calculated. For the second experiment, different masses were attached to the string, and the same method was used to calculate the period. Finally, the length was adjusted and the period was calculated in a similar manner. Data Tables
