# Structure Question – Oscillation

Diagram $$2.1$$ shows a loaded spring oscillating vertically in water. The oscillating system experiences damping.
Diagram $$2.2$$ shows the displacement-time graph for the oscillating system.

1. Underline the correct answer in the bracket to complete the sentence below.
Damping is a situation when the (amplitude, wavelength) of the oscillation decreases. [1 mark]
amplitude
2. State one reason why damping occurs in the oscillating system. [1 mark]
Energy lost due to friction.
3. Based on Diagram 2.2,
1. state the period of the oscillating system. [1 mark]
0.4s
2. what is the frequency of the oscillating system? [1 mark]
\begin{aligned}
f &=\frac{1}{0.4} \\
&=2.5 Hz
\end{aligned}

4. What will happen to the period of the oscillating system when a heavier load is used? [1 mark]
Increases
