(a)[1]
State what the frequency of an oscillating object’s motion means.
(b(i))[1]
Explain how Fig. 4.2 shows that the period of the oscillations is $0.80\,\text{s}$.
(b(ii))[2]
Calculate the angular frequency $\omega$ of the oscillations.
(b(iii))[3]
Besides the period, frequency and angular frequency of the oscillations, determine three other conclusions about the object and its oscillations that can be obtained from Fig. 4.1 and Fig. 4.2. The conclusions may be qualitative or quantitative. Use the space below for any working.
(b(iv))[3]
Describe the transfer between kinetic energy and potential energy during the oscillations. Numerical values are not needed.
