# Types of movement.

concept of movement is one of the philosophical categories, along with others, such as matter and time, are the basis for materialistic science.But since we are deeply seized of the matter will not.Just look at what are and what are the types of traffic from the point of view of classical mechanics.

In physics, there is a special section of mechanics - kinematics.She is studying mechanical movement and its species, with regards the movement itself is an object without its interaction with other bodies.Change the location of the body relative to the other at a given time is called the mechanical motion, which in Greek sounds like "Kinematics".

Movement permeated our whole life.Moving people and animals moving rivers and the air, the earth and the sun.It is quite possible that the original observation of the ancient Greeks for the process of moving, and subsequently led to the creation of a science like physics - at least to the creation of its sections, as mechanics and kinematics.

following types of mechanical motion: rotational, vibrational and translational.The translational movement is characterized by the fact that all the points of the body moving in the same direction by the same distance in the same time interval.When rotational motion or rotation of any point of the object are moved along circles whose centers are located on a line is called the axis of rotation.It called a vibrational movement, which periodically fully or partially repeated.

Considering the types of movement, we have introduced two concepts - the movement of the point and body.In fact, the description of the movement of the entire body is nothing else than the description of the motion of its various points.So often enough to characterize the movement of a point to understand the movement of the body.The translational motion is characterized by the same movement of all points of the body, so we can assume that, having considered the motion of a point, we have identified as the body moves.

However, all of the above types of movement are not limited.Movement can be straight or curved, uniform or uniformly accelerated.To describe the nature of the motion you must again introduce a new concept - the trajectory.It can be defined as a line along which the body moves.Drawing pen on paper, we can see a trail that is behind it.This is the path of movement of the pen.

Now, with the introduction of the concept of path, you can take a closer look at the types of movement previously noted.Thus, when the forward movement of the different points of the trajectory may be different, but they remain parallel to themselves.Examples are the body (but not the wheels) vehicle moving straight.The movement of the needle in a sewing machine or a piston in the cylinder motor - other examples of translational motion.

concept provides an explanation of the trajectory of rectilinear and curvilinear motion.If the trajectory is a straight line, this rectilinear movement - if not, then the curvilinear.As an example of the rotational movement can cause the curved Earth's rotation.Rotation is not reciprocating.

course, everything is given only a part of what you need to consider tapping the topic "Forms of the movement."For a full description of the character of the motion is necessary to introduce new concepts - such as speed, distance traveled, the system of reference.Then it will be a more detailed understanding of the nature of motion as a single point, and the body in general.But even given a bit of material makes it possible to look into the diverse world of movement.

The article deals made in classical physics, movement types, are examples of the different species and their features are described.
