To Determine the Spring Constant of a Helical Spring and a Value for the Earth's Gravitational Field Strength
A2 COURSEWORK
AIM:
To Determine the Spring Constant of a Helical Spring and a Value for the Earth's Gravitational Field Strength
OUTLINE: I will be using a coiled spring and using its elastic properties to determine a value for its spring constant and it's oscillating properties to calculate a value for the earth's gravitational field strength, to compare to the actual value for the earth's gravitations field strength.
*SPRING CONSTANT*
Hooke's Law states - "The Force a Spring Exerts on a Body is Directly Proportional to the Displacement of the System (The Extension of the spring)"
i.e. Force Extension
So... Force = K x Extension
F = Ke
So K = F/e
* For this experiment I will have to use the same spring throughout because the spring constant values vary from spring to spring.
