加拿大物理学论文代写:单位向量

毫无疑问,没有地区物理学中不使用向量的概念。我们的日常生活也是如此。从我们醒来到睡觉的那一刻起,向量就在我们生活的所有活动中都是显而易见的。一个人在早上跑步、开车、玩游戏,对飞机运动只是少数情况下,向量的应用在我们的日常行为。只要有需要描述一个量的方向和大小,载体是目前(jagtenberg,99-103)。这也许是物理学研究中最重要的工具之一,也是工程。现在我们可以看看一些常见的例子,它们与物理。

考虑一个块或肿块,滚下山坡。它是理想的估计在重力的作用下,块上的力和摩擦力。万有引力是向下的方向矢量,力是一个矢量,是90度的坡度和摩擦是在相反的方向运动(physicsclassroom.com,134-139.)。这是经典力学的一个例子。

同样地,电场和磁场是矢量量的场,其性质可以通过向量微积分运算来评估。量子力学与无限的向量空间,通过为单位向量或功能空间颗粒的位置(花边和招聘,349-375)。流体流经管道的速度是流体力学中的矢量和广义相对论中张量的一个例子。

我们将看到一些更复杂的例子,比如佳能,它是一个大炮,它使用炸药来发射弹丸。经不同的范围、口径、角度和发射率和发射功率,所有这一切都需要使用矢量。风是另一个常见的例子,有大小和方向。风的速度及其速度有助于描述在飞机或其他飞行物体中运动的其他元素的运动。

There is undoubtedly no area in physics that does not make use of the concept of vectors. The same is the case with our daily life. Vectors are visible and evident in all activities of our life right from the moment we wake up to the time we sleep. A person jogging in the morning, driving a car, playing a game, movement of an aero plane are just a few instances where vectors are applied in our day-to-day actions.  Wherever there is a need to describe the direction of a quantity along with its magnitude, vectors are present (Jagtenberg, 99-103). It is perhaps one of the most critical tools in the study of physics and also engineering. We may now look into some common examples and relate them to physics.

Consider a block or a mass that is rolling down a slope. It is desired to estimate the force of the gravity, the force on the block and the force of friction. The gravitational force is a vector in the downward direction, the force is a vector that is at 90 degrees to the slope and the friction is in the direction opposite to that of the motion (Physicsclassroom.com, 134-139). This is an example of classical mechanics.

Similarly electric and magnetic fields are field in vector quantities with the properties that may be evaluated through vector calculus operations. Quantum mechanics deals with infinite vector spaces through particulate positions as unit vectors or functional spaces (Lacy & Kershner, 349-375). The velocity of the fluid flowing through a pipe is an example of a vector in fluid mechanics and general relativity in tensors as well.

We shall see some more complex examples like a canon that is a artillery piece that uses explosives in order to present a projectile. Canons vary in range, caliber, angle and rate of firing and the power of firing, all of this requiring the use of vectors. Wind is another common example that has a magnitude and direction. The force of the wind blowing along with its velocity helps in describing the motion of other elements moving in air like a plane or any other flying object.
