Physics Degree

Bachelor Degree - Engineering
A bachelor degree in engineering is not something that is all that easy to get. The sciences are some of the most demanding disciplines of college. So if you're thinking of getting a bachelor degree in engineering, you better be prepared for what's ahead. Hopefully, this article will give you a decent idea of what is required to get that very demanding degree.

In many college curriculums, there is a lot of room for what they call "light" electives. In the case of engineering, or for that matter, any science, this is not so. The course outline for a degree in engineering is quite intense. Your electives are not going to be much easier than your required engineering courses.
Your first year will usually start off with basic introductory engineering courses for the first two semesters. A degree in engineering is a BS degree, which has tougher requirements that a BA degree. The supporting courses are much tougher. In addition to taking your introductory engineering courses in your first two semesters, most colleges will also require you to take two semesters of Calculus or a math equivalent and two semesters of physics. Some colleges will allow you to substitute chemistry for physics. Right there, between just those three courses, is half of your first year in college. You will also be required to take geometry courses as well.
The second year is almost a carbon copy of your first year. You'll be expected to continue with your engineering courses and take the last two semesters of Calculus and physics or chemistry in order to get your core requirements for your science courses. The remainder of the year is dedicated to your electives. Some colleges however, require that you take some kind of mechanical drawing. Engineering requires a lot of drawing so expect to take a lot of these courses throughout your four years.
Now is when it gets a little complicated. See, there are many different types of engineers, such as civil engineers, electrical engineers, mechanical engineers, etc. By your third year, most colleges require you to declare which engineering degree you are going for. After you declare this, that's when you get the remainder of your schedule for the last two years. And yes, this schedule will be drastically different based on what type of engineer you want to become because the skill requirements for each type of engineer are quite different. One thing that most people are surprised to hear is that a major requirement of any engineering degree is a basic course in English. Why? Engineers do a lot of writing. Many things need to be communicated in basic English. Because of the advanced nature of this information, or what people call "tech-speak" it is critical that an engineer has a good command of the English language.
Getting a bachelor degree in engineering is not an easy thing to do. But the rewards of getting one are certainly worth the effort it will take to get that piece of paper handed to you at the end of your four years.

One Dimensional Kinematics

Introduction to the Language of Kinematics

A typical physics course concerns itself with a variety of broad topics. One such topic is mechanics - the study of the motion of objects. The first six units of The Physics Classroom tutorial will involve an investigation into the physics of motion. As we focus on the language, principles, and laws which describe and explain the motion of objects, your efforts should center around internalizing the meaning of the information. Avoid memorizing the information; and avoid abstracting the information from the physical world which it describes and explains. Rather, contemplate the information, thinking about its meaning and its applications.

Scalars and Vectors

Physics is a mathematical science. The underlying concepts and principles have a mathematical basis. Throughout the course of our study of physics, we will encounter a variety of concepts which have a mathematical basis associated with them. While our emphasis will often be upon the conceptual nature of physics, we will give considerable and persistent attention to its mathematical aspect.

he motion of objects can be described by words. Even a person without a background in physics has a collection of words which can be used to describe moving objects. Words and phrases such as going fast, stopped, slowing down, speeding up, and turning provide a sufficient vocabulary for describing the motion of objects. In physics, we use these words and many more. We will be expanding upon this vocabulary list with words such as distance, displacement, speed, velocity, and acceleration. As we will soon see, these words are associated with mathematical quantities which have strict definitions. The mathematical quantities which are used to describe the motion of objects can be divided into two categories. The quantity is either a vector or a scalar. These two categories can be distinguished from one another by their distinct definitions:

* Scalars are quantities which are fully described by a magnitude (or numerical value) alone.
* Vectors are quantities which are fully described by both a magnitude and a direction.

The remainder of this lesson will focus on several examples of vector and scalar quantities (distance, displacement, speed, velocity, and acceleration). As you proceed through the lesson, give careful attention to the vector and scalar nature of each quantity. As we proceed through other units at The Physics Classroom Tutorial and become introduced to new mathematical quantities, the discussion will often begin by identifying the new quantity as being either a vector or a scalar.

Distance and Displacement

Distance and displacement are two quantities which may seem to mean the same thing yet have distinctly different definitions and meanings.

* Distance is a scalar quantity which refers to "how much ground an object has covered" during its motion.
* Displacement is a vector quantity which refers to "how far out of place an object is"; it is the object's overall change in position.

To test your understanding of this distinction, consider the motion depicted in the diagram below. A physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North.

Even though the physics teacher has walked a total distance of 12 meters, her displacement is 0 meters. During the course of her motion, she has "covered 12 meters of ground" (distance = 12 m). Yet when she is finished walking, she is not "out of place" - i.e., there is no displacement for her motion (displacement = 0 m). Displacement, being a vector quantity, must give attention to direction. The 4 meters east is canceled by the 4 meters west; and the 2 meters south is canceled by the 2 meters north. Vector quantities such as displacement are direction aware. Scalar quantities such as distance are ignorant of direction. In determining the overall distance traveled by the physics teachers, the various directions of motion can be ignored.

Now consider another example. The diagram below shows the position of a cross-country skier at various times. At each of the indicated times, the skier turns around and reverses the direction of travel. In other words, the skier moves from A to B to C to D.

Quiz
Use the diagram to determine the resulting displacement and the distance traveled by the skier during these three minutes. Then click the button to see the answer.

Answer :
The skier covers a distance of

(180 m + 140 m + 100 m) = 420 m

and has a displacement of 140 m, rightward.

Speed and Velocity

Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity which refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. A slow-moving object has a low speed and covers a relatively small amount of distance in a short amount of time. An object with no movement at all has a zero speed.

Velocity is a vector quantity which refers to "the rate at which an object changes its position." Imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. While this might result in a frenzy of activity, it would result in a zero velocity. Because the person always returns to the original position, the motion would never result in a change in position. Since velocity is defined as the rate at which the position changes, this motion results in zero velocity. If a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. Every step must go into moving that person further from where he or she started. For certain, the person should never change directions and begin to return to the starting position.

Velocity is a vector quantity. As such, velocity is direction aware. When evaluating the velocity of an object, one must keep track of direction. It would not be enough to say that an object has a velocity of 55 mi/hr. One must include direction information in order to fully describe the velocity of the object. For instance, you must describe an object's velocity as being 55 mi/hr, east. This is one of the essential differences between speed and velocity. Speed is a scalar quantity and does not keep track of direction; velocity is a vector quantity and is direction aware.



Acceleration

The final mathematical quantity discussed in Lesson 1 is acceleration. An often confused quantity, acceleration has a meaning much different than the meaning associated with it by sports announcers and other individuals. The definition of acceleration is:

* Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Sports announcers will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity, then the object is not accelerating. The data at the right are representative of a northward-moving accelerating object. The velocity is changing over the course of time. In fact, the velocity is changing by a constant amount - 10 m/s - in each second of time. Anytime an object's velocity is changing, the object is said to be accelerating; it has an acceleration.

Physics Reference Book For the Scientist - Book Review

Most Americans have a pretty good understanding of physics. After all, we all understand gravity, and we know what happens when we turn on the stove and boil water. We also know when we go around the corner too fast in our car everything leans to one side. And most young men have played baseball at sometime in their life so they have a pretty good idea of force, power, kinetic energy, and object's trajectory. All this is "physics" of course.

Still, what if you are a scientist and you understand all that but you need to know or all there is to know, all the mathematical formulations and exactly how everything affects everything else in a scientific way? If these are things that you need to know, then perhaps I can recommend a very good book to you. This is a book that I have in my personal library and I use quite often when coming up with new concepts, innovations, or inventions. The name of the book he has;

"Physics for Scientists" by Randall K. Knight.

This is a reference book for Scientists on the realm of physics. It helps scientists so they don't make any mistakes when they're conceiving a new idea or pushing the limits of thought with new concepts. It's a very excellent book and it makes a nice addition to the library for a graduate physics student or someone that has been studying physics all their live and has some revolutionary new ideas.

The book is fully illustrated, and it is very good. I recommend it to anyone that is involved in the scientific fields, even rocket scientists. I hope you will please consider all this.

Online Range Ecology Degree Courses

Range (also known as range lands) is a barren land that is not fit for agriculture and cultivation. Range land is mainly utilized as a source of continuous forage for cattle. Ranges can also provide natural resources like minerals and timber. Also these can be utilized as spaces for recreation and enjoyment. An ideal range land should provide almost all of the above-mentioned utilities. For making a range land ideal for all these purposes, a stream of science has emerged. It is called the management of range ecology. Generally the management of range ecology is associated with environment and agriculture.





There are a number of universities and educational institutions in United States that offer courses in management of range lands. Montana State University, University of Idaho, Oregon State University, Colorado State University, Texas A and M University are some of the major universities in United States that provide excellent bachelor-level and post-graduate courses in range management. As the specialization of range ecology and management has good career prospects with various government and ecological organizations, the number of students opting for range management course has been continuously on the rise.

With personal computer and internet becoming common household accessories, the idea of distance education has gained a new dimension. Many technologically advanced universities started providing online learning facility for their regular courses. The university then sends notes and lectures through e-mail. Some universities even arrange video conferencing facility for simulating real-life class-room learning atmosphere. Although range ecology and its management is not a common and conventional specialization like bio-technology or molecular physics, there are several universities that allow students to pursue studies on range ecology and its management through internet.
The Animal and Range Sciences Department of Montana State University provides an excellent online degree course on range ecology. The department offers diverse research and training material in range ecology, habitat management, watershed management, grazing management and plant-animal interactions. University of Idaho also offers an online degree course on range ecology. Similarly Oregon State University provides an online degree course and management with a curriculum that is intended to prepare students to think about the range ecology critically and comprehend the mutually beneficial interactions between living species and soil. Colorado State University has a bachelor-level study program and management that emphasizes on biodiversity, environmental ethics, environmental planning, and range management.
