An investigation into the effects of a force applied to a spring and the time for it to complete a set number of oscillations

Plan

Intro: I am going to investigate the effects of a force applied to a spring and its relationship to the time it takes for the spring to complete a set number of oscillations, when the displacement is constant. While conducting this investigation, I will always bear in mind, that I would like my results to be as accurate and reliable as possible. I have also previously conducted an investigation into the elasticity of a spring, which showed me that the force applied to a spring and its extension as a result of the force applied is directly proportional or constant. Could this imply that the frequency or the oscillations per second have a constant relationship to the force applied also?

Safety

Safety is paramount in all scientific investigations and this will be no exception. All masses and weights will be handled with care. Masses will not exceed the spring's maximum tolerance so there is no danger of the springs wire breaking. Food will not be consumed in the laboratory nor will drinks be drunk. People will not run in the laboratory. Safety spectacles will be worn so that if, by some unforeseen reason, the spring were to break, eyes will be kept safe.

Fair test

This will be a fair test by all other variables, within my control, being kept constant. The temperature for this investigation will be room temperature, approximately 23?C. The same spring will be used. The same displacement for the spring will be used. The same spring will be used because of differences in the spring constant. The number of oscillations the spring hast to complete will always be 10.

Scientific knowledge

When using springs in an investigation, it helps to revise/research a law called Hooke's Law. This is a formula that states that the force acting on a spring and the spring extension have a constant relationship. Which can be expressed by the simple equation:

F=KX

Force=constant x extension

Using this formula, we can find the constant of the spring if we know the extension and force acting on it by rearranging the equation

K=F/X

Constant=Force / Extension

and the formula can also be rearranged so that extension becomes the subject:

X=F/K

Extension =Force / Constant

F= Force

K= Constant

X= Extension

I believe that momentum is also worth mentioning here because I think that momentum is what will have the time delaying effect on the spring's oscillation time. Momentum is an object acting under its own kinetic energy that has stored. If an object was to be accelerated, kinetic energy being transferred into the object, and then to stop accelerating and for external forces to stop acting on it, the object can continue to move under its own kinetic energy until the energy is transferred into other objects or particles, in the case of air resistance. Momentum can be expressed by the simple formula:

Momentum = mass x velocity

Kg per m/s2 = kg x m/s
