A mass attached to a spring is drawn back 2 cm from equilibrium and released. If a second spring were used that had a smaller spring constant than the first but the mass was the same, which of the following would be larger?
A) Amplitude
B) Frequency
C) Period
D) Initial restoring force

Quizplus · Accepted Answer

The period of oscillation of a mass-spring system is given by $T = 2\pi\sqrt{\frac{m}{k}}$, where $m$ is the mass and $k$ is the spring constant. A smaller spring constant ($k$) would result in a larger period ($T$), as they are inversely proportional in the equation.
