Physical phenomena are observable events that occur in nature, governed by the laws of physics. These phenomena can include a wide range of occurrences, such as gravity, electromagnetism, and thermodynamics. They help us understand how matter and energy interact in the universe, from the falling of an apple to the ground to the behavior of light. Examples of physical phenomena include waves, which can be seen in the ocean or heard as sound, and motion, which describes how objects move through space. Studying these phenomena allows scientists to develop theories and technologies that improve our understanding of the world around us.
