The spring itself is also oscillating. It is found from calculus techniques that one-third of the mass of the spring must be added to the suspended mass in calculations using the equation in the background section. Calculate the total mass (suspended mass plus effective mass of the spring). Calculate the period based on the spring constant and the total mass. Calculate the percent difference.
