The nature consists of diverse bodies, which we call physical bodies. All the bodies that surround us consist of a substance. Some physical bodies are made of one substance and some of several types of substances. For example, the...
The simplest example of straight linear motion is the straight line movement at constant speed. A linear movement is a movement where the body travels equal lengths during the same amounts of time.
Example: A car has passed the lengths...

If we select a measuring unit for each size, we get a system of measuring unit.
Today we have a unique international system where for each size there is a precisely defined unit of measure. This is called International System...
Aristotle (384-322) studied many fields like philosophy and the natural sciences. Among other things, he studied the movement. He thought that the natural place of the air is up and the water was down. Although his theory is not...
Mechanics is a part of physics that deals with the study of the mechanical movement of the body and its interaction with other body. In order to study mechanical motion, it is necessary to determine the position of the...
Area
The surface area represents a physical size of a body that is obtained by multiplying its length and width. Before calculating the surface area, it is necessary to measure the length and width of the rectangles. If it's a...
Third Newton's law is often called the Law of Action and Reaction. And the law explains the nature of force between two interaction bodies that have equal magnitude and the opposite directions.
If the force comes from one body and...
Gravitational Interaction
Gravity is an invisible force that draws all the bodies in the Universe to each other. Solar gravity keeps the planets in their orbits. Earth's gravity 'ensures' that the Moon circulates in its orbit around the Earth. The...
Research of the natural sciences began in ancient times. Some important discoveries in physics came from a theoretical approach, and on the other hand, some discoveries resulted from the experiment. Some discoveries occurred by an accident or as a...
