The figure shows the axis of the traveled path and the value of time in seconds.
During the movement of cars we measure the length of the road (distance) and the time of movement.
When we apply the time expressed in...
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...
When we hold an item in our hand, it presses our hand downwards. The force by which the body presses the horizontal surface on which it stands is called the weight of the body.
The gravity force and the weight...
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...
What size do we measure when a body moves? How long have we been traveling? How much far we have traveled? How fast have we arrived? The following sizes we measure when moving:
Preceeded Way - The part of the...
In nature, we rarely encounter uniform movement. Usually, the bodies change the speed of movement during their movement.
Before starting to move, the speed of the car is zero. At the beginning of the movement this speed increases. When approaching...

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...
They studies of movement dates since the ancient Greece. For instance, Aristotle had an opinion that the bodies moves and that movement was created as a consequence of the natural order of things, such as that the natural place...
It is clear that it is not enough to use only one measuring unit for a particular physical size. So offten, besides basic units, larger and smaller units of measure are introduced.
To indicate these units, we use prefixes that...
