Calculating the value of "g" (Gravitational field strength) using a mass on a spring Gravity affects all things that have mass and therefore must affect how much a mass placed on a spring will extend. Measuring the time period and extension of a mass on a spring for vibrations should enable us to calculate a value for g. Using the following formula will help us to do this: Formula 1 T=2?Vm/k g (gravitational field strength) affects the spring constant - k in the formula F=ke and because F = weight = mg. Therefore mg = ke and m/k = e/g. We can now change formula 1 to the following: T=2?Ve/g If we rearrange the above formula so that the subject is T2 we should get the formula below: T2 = 4?2 e g Measuring T would allow us to calculate T2 (The time period - to calculate measure the time it takes for a certain number of oscillations and...
