Period of Mass-Spring System

A mass and spring system is a type of simple harmonic oscillator
The?time period?of a mass-spring system is given by:

6.2.4-Mass-Spring-Time-Period-Equation

Where:
- T?= time period (s)
- m?= mass (kg)
- k?= spring constant (N m-1)
This equation applies for both a horizontal or vertical mass-spring system

6.2.4-Vertical-Horizontal-Mass-Spring-System

A mass-spring system can be either vertical or horizontal. The time period equation applies to both

The equation shows that the time period and frequency, of a mass-spring system, does?not?depend on the force of gravity
- Therefore, the oscillations would have the same time period on Earth and the Moon
The higher the spring constant?k, the stiffer the spring and the shorter the time period

Worked Example

Calculate the frequency of a mass of 2.0 kg attached to a spring of spring constant 0.9 N m–1?oscillating in simple harmonic motion.

Exam Tip

Another area of physics where you may have seen the spring constant?k?is from Hooke's Law. Exam questions commonly merge these two topics together, so make sure you're familiar with the Hooke's Law equation too.
