### History of Physics – Movement and Gravitational Interaction

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...

### Dynamics – Newton’s Laws

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...

### International System of Units (SI)

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...

### Motion Along a Straight Line

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...

### The Surface Area and the Volume

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...

### WHY WE LEARN PHYSICS?

Physics is one of the basis of natural science. It is in our every day life even though we are not always aware how often we apply the laws of physics and in which extent it determines our lives....

### Graphical representation of speed in uniform motion

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...

### 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...
