Since ancient times, people have collected information about the world in which they live. There was only one science, combining all the information about nature that humanity had accumulated at that time. Then people still did not know that they were observing examples of physical phenomena. Currently, such a science is called "natural science."
What physics studies
Over time, scientific ideas about the world around us have changed markedly - there are much more. Natural science has split into many separate sciences, among which: biology, chemistry, astronomy, geography and others. In some of these sciences, physics is not the last place. Discoveries and achievements in this area have allowed humanity to possess new knowledge. These include the structure and behavior of various objects of all sizes (starting with giant stars and ending with the smallest particles - atoms and molecules).
The physical body is ...
There is a special term “matter”, which in the circles of scientists calls everything that is around us. A physical body consisting of matter is any substance that occupies a certain place in space. Any physical body in action can be called an example of a physical phenomenon. Based on this definition, we can say that any object is a physical body. Examples of physical bodies: button, notepad, chandelier, curtain rod, moon, boy, clouds.
What is a physical phenomenon?
Any matter is in constant change. Some bodies are moving, others are in contact with the third, the fourth are spinning. Not for nothing many years ago, the philosopher Heraclitus uttered the phrase "Everything flows, everything changes." Scientists even have a special term for such changes - these are all phenomena.
Physical phenomena include everything that moves.
What types of physical phenomena exist
These are phenomena when, due to the effect of temperature, some bodies begin to transform (shape, size and condition change). An example of physical phenomena: under the influence of the warm spring sun, icicles melt and turn into liquid, with the onset of cold weather the puddles freeze, boiling water becomes steam.
These phenomena characterize a change in the position of one body in relation to the rest. Examples: the clock goes, the ball jumps, the tree sways, the pen writes, water flows. All of them are in motion.
The nature of these phenomena fully justifies its name. The word "electricity" is rooted in the Greek language, where "electron" means "amber." The example is quite simple and probably familiar to many. With a sharp removal of a woolen sweater, a small crack is heard. If you do this by turning off the light in the room, you can see sparks.
A body participating in a phenomenon that is associated with light is called luminous. As an example of physical phenomena, we can cite the well-known star of our solar system - the Sun, as well as any other star, lamp or even a firefly bug.
Sound propagation, the behavior of sound waves in collisions with an obstacle, as well as other phenomena that are somehow related to sound, belong to this type of physical phenomena.
They are due to light. So, for example, man and animals are able to see, because there is light. This group also includes the phenomena of propagation and refraction of light, its reflection from objects and passage through different media.
Now you know what physical phenomena are. However, it should be understood that there is a certain difference between natural and physical phenomena. So, with a natural phenomenon, several physical phenomena occur simultaneously. For example, when lightning strikes the earth, the following phenomena occur : magnetic, sound, electrical, thermal, and light.
