The Millionaire Guide On Some Key Terms Of Linear Motion. To Help You Get Rich.




Introduction:
Motion of living objects  and non-living matter  is one of the main branches of physics. It has a wide range of application in wide range of fields like as medicine, geology, and sport science, engineering   among others. When we drive or we   are driven, fly in the air ,walk, jog or when we are  doing exercise  of some kind are all  forms of motion. When in this condition, routinely one is paying attention in how much longer, when, and how quickly one can get to his / her target. Having answers to these and comparable questions would be very helpful to individuals, and this is precisely the discussion of this topic. In this present topic, we will be taking into account motion in one dimension called linear motion. In other words, concentration is only given to vertical, horizontal and any other forms of straight line motion, such as motion on an inclined surface. Furthermore, motion will be considered without making reference to its causes, i.e. forces. This is to say that this topic deals with kinematics; dynamics on the other hand will be dealt with in the nearest future – keep fingers crossed. One another thing which I would like to add here is that, for this topic we will keep our conversation brief and spotlight more on the examples.
 Variables [Quantities]       

Let us we  take few minutes to review the concepts of  variables or those terms which are  usually used in this topic. By a variable, we know that it means “what varies” obviously, but more specially it assigns to those physical quantities which we measure. So here are some those variables which are  commonly worn in this topic.
Here we have :
Distance:


Æ Distance is a change in place as compared to a reference point or zero point.
Æ It is a scalar2 quantity
Æ Measured in metre3 (m)
Æ It can only be positive.
 Displacement:

Displacement is a alter in position relative to a reference (or zero) point in a particular direction.
µ It is a vector4 quantity and measured in metre (m).
 A variety of  letters are worn to symbolize equally displacement and distance, but the most
2 It is a physical quantity which has [or is characterized with] a magnitude only.
3 This is the basic SI unit for distance, but other units can also be recycled or found in use.
4 It is a physical quantity that has (or is described with) both  magnitude and  direction. As an  outcome it may have positive or negative  value depending on the selected direction of orientation A positive sign is usually misplaced but a negative value is designated except if this acts with a word or term which announce such.
