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...
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...
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...
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...
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...
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...
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...
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...
