When particles in water become part of a wave, they start to move up or down. This means that kinetic energy(energy of movement) has been transferred to them. As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down. This means that some of their kinetic energy has been converted into potential energy – the energy of particles in a wave oscillates.
Thinking about potential energy can help us understand why tsunamis can be so damaging. When a tsunamiapproaches the shore, it shoals (becomes much higher), so the water particles are displaced further from equilibrium. They acquire a lot of potential energy, and this is released when the wave interacts with land. between kinetic and potential energies.
