Colored scalars and vector

24.12.2020 By Voodoobei

Designers, webmaster, and marketers that are starting out find it difficult to understand the difference between Raster and Vector graphics. The vector image consists of mathematical formulas that control the path of the image. Image creation can be a difficult task with a Vector image. They are created in the form of a Vector format. Though the Vector images are less detailed they offer precise paths.

Vector images can be transformed into Raster graphics to port between systems. Raster images offer detailed editing. Converting a Raster image to a Vector image is complicated and time-consuming.

Also, converting Raster to Vector is unnecessary as the printed images or photos captured with a digital camera are in Raster format. In Vector images the resolution is formed by numerous paths. These paths are defined in terms of proportions, ratio, height, width, and other dimensions.

When you resize a Vector image the mathematical equations recalculate the curves, lines, and nodes, so the image remains sharp and clear. Their size is always fixed so if you expand a Raster image it will become blurry. If you want to preserve the quality of a Raster image you can only scale down the image. Vector images are infinitely scalable as the mathematical formulas change when you resize the image. They retain their clarity and sharpness even when you enlarge the image.

If you look closely at a Vector image you will see seamless curves and well-defined lines. A Raster image is not scalable as they have a fixed resolution and dimensions.

The pixels get enlarged if you try to zoom the image that makes the image blurry. You can always scale down a Raster image to maintain its quality. If you look closely at a scalar image you will see many equally sized squares. Vectors images are smaller in file size as their dimensions are controlled by mathematical formulas.

This makes them suitable for transmission, also they carry a lot of data in small file sizes. Raster files are heavier with very little information.

This makes them inconvenient for mass use in multipurpose projects. When you create an image with Vector programs the file types will be. Raster images are compatible with all recognizable and popular software.

This makes them suitable for mass use in multipurpose projects.What is the difference between distance and displacement? Whereas displacement is defined by both direction and magnitude, distance is defined only by magnitude. Displacement is an example of a vector quantity. Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction.

Vectors are represented graphically by arrows. An arrow used to represent a vector has a length proportional to the vector's magnitude e. Some physical quantities, like distance, either have no direction or none is specified.

A scalar is any quantity that has a magnitude, but no direction. In this case, the minus sign indicates a point on a scale rather than a direction. Scalars are never represented by arrows. In order to describe the direction of a vector quantity, you must designate a coordinate system within the reference frame. For one-dimensional motion, this is a simple coordinate system consisting of a one-dimensional coordinate line.

In general, when describing horizontal motion, motion to the right is usually considered positive, and motion to the left is considered negative. With vertical motion, motion up is usually positive and motion down is negative.

In some cases, however, as with the jet in Figure 2. For example, if you are analyzing the motion of falling objects, it can be useful to define downwards as the positive direction. If people in a race are running to the left, it is useful to define left as the positive direction. It does not matter as long as the system is clear and consistent. Once you assign a positive direction and start solving a problem, you cannot change it. A person's speed can stay the same as he or she rounds a corner and changes direction.

Given this information, is speed a scalar or a vector quantity? Speed is a scalar quantity. It does not change at all with direction changes; therefore, it has magnitude only. If it were a vector quantity, it would change as direction changes even if its magnitude remained constant. A fundamental tenet of physics is that information about an event can be gathered from a variety of reference frames. For example, imagine that you are a passenger walking toward the front of a bus.

As you walk, your motion is observed by a fellow bus passenger and by an observer standing on the sidewalk. Both the bus passenger and sidewalk observer will be able to collect information about you.

They can determine how far you moved and how much time it took you to do so.If you're seeing this message, it means we're having trouble loading external resources on our website. To log in and use all the features of Khan Academy, please enable JavaScript in your browser.

The underlying concepts and principles have a mathematical basis. Throughout the course of our study of physics, we will encounter a variety of concepts that 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.

The motion of objects can be described by words. Even a person without a background in physics has a collection of words that can be used to describe moving objects. Words and phrases such as going faststoppedslowing downspeeding upand 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 distancedisplacementspeedvelocityand acceleration.

As we will soon see, these words are associated with mathematical quantities that have strict definitions. The mathematical quantities that 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:. 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.

To test your understanding of this distinction, consider the following quantities listed below.

What is the difference between a scalar, vector, matrix and tensor in simple terms?

Are vector fields and tensors related? A matrix is an array of numbers used in linear algebra. Various classes of matrices might form groups and other fun mathematical structures, but a lone matrix is not much more than a mathematical object.

Scalars, vectors, and tensors, on the other hand, are geometric objects. What makes them important is that these are the geometric object we encounter in nature. They can be classified by how the transform under rotations. Scalars have the property of being completely spherically symmetric: they look the same no matter how you rotate them. Vectors, with their magnitude and direction, are the simplest non-trivial thing that can be rotated nicely under normal 3D rotations.

Tensors are more complicated: naively they transform like the dyadic product of 2 vectors, and that requires 2 application of a rotation, which gets messy for 2 reasons:. Wigner, Clebsch and Gordon, and others have addresses this. I find this to be the best way to understand their geometric nature esp.

What Are Vectors and Scalars? - Physics in Motion

The numerical representation of a geometric object is not the geometric object. The former is a coordinate dependent thing, while the geometric object itself exists independent of any coordinate system, and people do try to formulate the laws of physics in a coordinate-free manner. Another point of confusion is the notion, from computer science, that "scalar" means "number". While a number can represent a scalar, a number cannot be rotated: it is not a geometric object.

It's a pseudo scalar field. But it is not a number: if I reflect the coordinates it changes sign which is way I added "pseudo" to it. Numbers don't change signs. Scalar are not numbers. This view is useful in the development of coordinate-free laws of physics.If you're seeing this message, it means we're having trouble loading external resources on our website.

And they might sound like very complicated ideas, but we'll see over the course of the videos that they're actually very simple ideas.

So first I'll give you a little bit of a definition. And then I'll give you a bunch of examples, and I think the examples will make things super clear.

Hopefully, they'll make things super clear. A vector is something that has a magnitude, or you could kind of view that as a size, and it has a direction. So "and" it has a direction. A scalar only has a magnitude, or size. And if that doesn't make sense to you, it will hopefully make sense to you in a second when I show you an example.

For example. Let's say that I have, let's say that that's the ground-- let me do the ground in a more appropriate ground-like color. So this is green right over here. And let's say that I have a brick here. I have a brick on the ground. And I pick up that brick, and I move it over to this place right over here.

So I move the brick right over there. And then I take a ruler out, and I say, wow, I've moved the brick 5 meters. So my question to you, is my measurement of 5 meters, is it a vector or a scalar? Well, if I just tell you 5 meters, you just know the size of the movement. You just know the magnitude of the movement. So if someone were to just say 5 meters, this is a scalar quantity.
