I. Introduction
Simple harmonic motion is a type of oscillation, which is undampened and
undriven. It is periodic, represented by equations for displacement, velocity, and
acceleration involving the sine and cosine functions. Specific examples of simple
harmonic motion include masses oscillating on springs, simple pendulums, and physical
pendulums. In this lab, we used the first example of simple harmonic motion; a mass
oscillating on a spring. For our experiments, we some vital equations included:
ω=
√
M/k,
ω=2π/T
and therefore
T = 2π*ω = 2π*
√
M/k.
In this equation, M represents the mass
hanging from the spring, while k represents the spring constant.
II. Procedure
This lab consisted of three parts. In part one, we hung three different springs on a
stable rod. We then attached different known masses to the end of the spring and
measured the distance of the equilibrium position of the mass to the floor. Graphing these
results gave us values for the spring constants of each spring. In part two of this
