Introduction:
Addition of vectors:
Let [vecOA] = [veca] and [vecAB] = [vecb]
The [vecOB] represents the addition of [veca] and [vecb]
We mention that [vecOB] = [vecOA] + [vecAB]
[vecOB] = [vecOA] + [vecAB]
= [veca] + [vecb]
Subtraction of vectors:
If [veca] and [vecb] are two vectors, then the subtraction of [vecb] from [veca] is defined as the vector sum of [veca] and − [vecb] and is denoted by [veca] − [vecb] .
[veca] − [vecb] = [veca] + ( − [vecb)]
Properties of Addition and Subtraction of Vectors:
Space:
An amount having only magnitude is called a scalar. It is not related to any permanent way in space.
Examples:
* Mass
* Volume
* Density
* Work
* Temperature
* Distance
* Area
* Real numbers.
Properties for addition of vectors:
Property 1: Vector addition is cumulative.
If [veca] and [vecb] are any two vectors then [veca] + [vecb] = [vecb] [veca]
Property 2: Vector addition is associative.
For any three vectors [v...

An object remains at rest, or in motion, unless an external force acts upon it.
Parallax is defined as “any alteration in the relative apparent positions of objects produced by a shift in the position of the observer” (Columbia Electronic Encyclopedia 1). Parallax is commonly used to measure distances between celestial bodies, such as planets and stars. Parallax is measured using angles that are much smaller than a degree. Arcminutes are one sixtieth of a degree and arcseconds are one sixtieth of an arminute. One example of the infinitesimal size of an arcsecond could be the width of a dime from a point of view two kilometers away (“Cool Cosmos”). These units of measurement are used in the parallax formula, or the formula used to calculate distance when given an object’s parallax measurement. The distance given from the parallax formula is in parsecs, which are 3.26 light years or 3.18x10^13 kilometers (“PARALLAX”). The parallax formula can be written as “distance = 1/parallax” (“PARALLAX”).
Momentum is defined as the product of mass and velocity on a body. It is a vector quantity and is measured in kg.m.s-1 (M.Mann, 2013).
When the above calculations are expanded from left to right, new assumptions are introduced by each
Going back to the history of VE, In1947 VE methodology was initially implemented as “value analysis” by Lawrence Delos Miles in order to make grounding material to increase product value. It was used to indicate to the study of the product during the design stage (WCL, 2014) and “uses a value equation that says value is equal to function divided by cost” (Elayache, 2010). This equation calculates the functionality of the project in relation to the total cost of the project (all construction cost plus running cost)
Pythagoras’s theorem proves that a2 + b2 = c2 but his theorem is only applicable for right-angled triangles. Although isosceles are capable of being right-angle triangles because two of the sides are equal length the formula does not work.
We are motivated by a desire to complete our subjective experience by inventing new aesthetic and conceptual capabilities. We are not in the least surprised, however, to find physicists and mathmaticians working simultaneously on a metaphor for space in which paradoxical three dimensional experiences are resolved only by four dimensional space. Our reading of the history of culture has shown us that in the development of new metaphors for space artists, physicists, and mathmaticians are usually in step” – Tony
The main reason the metric system is known for its simplicity is because there is only unit of measurement or a base unit for each type of measured quantity measured; length mass, weight, etc… There are a few base units in the metric system but the most common ones which are used are the meter, gram and liter. As an example if ...
In our text we began our study of physics with motion because motion is a dominant characteristic of the Universe (Kirkpatrick, 21). In class we learned that speed is the distance traveled divided by the time taken, s=d/t. The definition of velocity is very close to that of speed except that direction of an object is also taken into account.
Equilibrium in the reaction can be shifted towards the formation of the addition product by using sulfuric acid to drive the reaction.
Value engineering is also referred to as "value management" or "value methodology" (VM), and "value analysis" (VA). VE is a structured problem-solving process based on function analysis—understanding something with such clearness that it can be described in two words, the active verb and measurable noun
Space has always been a pivotal and utmost important subject for many years. In the past, scientists have made monumental advances in this field such as sending people into orbit and landing a man on the moon. Of course, this has only barely been explored and we still have a lot more to see of the ever-vast outer space. One of the most significant topics of all of science has only been touched and there’s still more to come.
