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...
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...
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...

Free Fall

If some body is being dropped, it will start falling down towards the Earth's surface. It has been determined experimentally that all bodies have the same speed if they fall through the space that has no air. Any two...
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...
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...
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...

Prefixes

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...
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...

Dimensions

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...
