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...
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...
As the history of people tried to measure the physical quantities and used the measurement units and instruments for measurement. The development of traffic has led to the connection between the countries. Thus, the need for the introduction of...
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...
  Newton's Second Law is one of the basic laws of mechanics. And it speaks about how much acceleration a body mass m gets if the force F is affected by it. The body moves at a constant speed or...

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...
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...
A body lying on the ground will not run on its own. Not even a small ball on the table or the ball on the grass, will not start until a it is moved by a force. On the...
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...
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...
