Introduction

Research Question:

This investigation asks the question of what the effect of changing the mass on the period of oscillation of a mass on a spring.

Independent Variable:

The independent variable is the time for one period of oscillation. The time for five period oscillations will be measured in seconds which will be recorded through the utilisation of a stopwatch.

Dependent Variable:

The dependent variable is the mass that will be added to the spring to investigate its effect on for five period oscillations. Brass weights were used within this practical.

Controlled Variables

What will be controlled

How it will be controlled

Displacement

The displacement of the mass on the spring will always be pulled back 0.02m from its equilibrium/spring constant

Spring

The same spring will be used throughout the entire practical to ensure that the length, material and

External Factors

To minimize external factors such as air blowing against the spring, the experiment was held within a classroom with doors and
