A mass is hung on a spring as shown in the diagram. When the mass is pulled down

and released, it oscillates at the natural frequency of the system.

When the top of the spring is forced to move up and down at this natural frequency,

resonance occurs.

The system below is set up to observe what happens to the oscillations of the mass as

the frequency f of the vibration generator is varied.

State what you would observe as f gets close to the resonant frequency.

The amplitude of the oscillation increases

(b)
Add To Classified

As f is varied, the amplitude of oscillation A of the mass is recorded. The results are

shown on the graph.

(b) (I)

Use the graph to estimate the resonant frequency

Resonant frequency =                Hz

Maximum correctly read to 3 SF from properly drawn curve (1)

e.g. 1.60 Hz

Describe how you would improve the experiment to obtain a more accurate

value for the resonant frequency.

Take more readings 

At the turning point

Or Around the resonant frequency

Suggest why it would be better to use an ultrasound position sensor and data

logger to record the position of the mass.

More accurate

Or Reduces random errors

Or Reduces (percentage) uncertainty

Or Allows many more readings to be taken in a given time
