Introduction
An oscillating object is a mass that follows a pattern that causes the mass to return to its initial position after completing one complete oscillation in a constant certain amount of time. This experiment aims to show how the medium that a simple pendulum is traveling though affects the frequency of the pendulum.
Research Question
How does the medium that a simple pendulum is traveling though affect the frequency in the simple pendulum and how drastic is theta change?
Hypothesis
Based on what I know about traveling though different mediums the more optically denser medium will cause more resistance to the pendulum causing it to complete fewer cycles within one second then the less optically dense medium.
Variables
Controlled:
* Length of string between the mass on the pendulum * Amount of medium * Height of pendulum * Degree the mass is lifted too * Mass of pendulums mass’s * Weight of pendulums mass’s * Start the time at the same time as dropping the mass * Contain only the medium being tested no other contents
Independent: type of medium (air, water, classic coke, Fanta, Sugar Water)
Dependent: (T) Time taken for Pendulum to stop at PE.
Materials
* Clamp x1 * Stand for clamp x1 * Simple pendulum with a mass of 14g x1 * Water tight box of the clamp stand 46cm long*2.5cm wide*11cm high x1 * Protractor x1 * Stopwatch x1 * Material needed to record data x1 * Water 1897.5ml * Ethanol 1265ml * Sun Flower Oil 1265ml * Fruit syrup 632.5ml
Method
1. First set up the experiment, this requires you to fill the water tight box you picked out earlier with enough liquid to submerge the pendulum completely, to set up the pendulum, and to put together the compound pendulum on the clamp that will fit well with the water tight box, make sure that the pendulum will be completely submerged, also remember to make sure the syrup
