The question as text
An object is suspended from a vertical spring as shown in Fig. 3.1. spring object oscillation Fig. 3.1 The object is displaced vertically and then released so that it oscillates, undergoing simple harmonic motion. Fig. 3.2 shows the variation with displacement x of the energy E of the oscillations. –1.6 –1.2 –0.8 –0.4 0 0.4 0.8 1.2 1.6 0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 x / cm E / mJ P Q R Fig. 3.2 11 The kinetic energy, the potential energy and the total energy of the oscillations are each represented by one of the lines P, Q and R.
