As this sheet of water moves on and off the beach, it can “capture” and transport beach sediment back out to sea. This process, known as “longshore drift,” can cause significant beach erosion.
The sample with the lowest AVERAGE kinetic energy is the coolest one.
The sample with the lowest TOTAL kinetic energy depends on not only the temperature of the samples, but also on their size, since each molecule in the sample has kinetic energy.
