Introduction
相似的速度和物体的运动速度是运动和位移较前的位置在一个特定的时间。两个粒子的SI单位是m / s一米每秒。速度和速度都是依赖于覆盖的距离,总时间和运动的方向。的差异也在这两个方面的计量单位。速度和速度的计量单位是米/秒。
What is speed?
Figure 1: Speed and velocity
速度是指总距离由一个对象在一个特定的时期。缺乏不同定向组件指的是标量。为了测量一个物体的平均速度依赖于行驶距离。它也被称为一个物体的速度和距离变化的速度。速度可以零在任何情况下,一个物体的速度从来不是消极的。速度是平均速度的公式=总行驶距离/时间(徐et al . 2020年)。
例如,当一辆车与一辆自行车并排移动的同时,然后计算总距离的速度覆盖的车辆在一个特定的时间。
What is velocity?
Figure 2: Velocity
速度是指对象的direction-aware随着位置变化的速率。它属于矢量的大小和方向。速度是衡量的不同速度的差异。它可以用公式计算平均速度=位移/时间。速度可以是零或消极以及积极。例如,动车返回后其主要位置覆盖距离汽车的速度将是零。
速度是一个物体的速度驱动方向相同(徐et al . 2020年)。测量速度的公式是$ mathrm {v =:δx: /δ:师:}v代表速度,美元美元mathrm{δx:}是指物体的位移和美元mathrm{δt:} $表示到达时间。
Different types of speeds
速度可以分为几个类别,如瞬时、平均、理性以及切向速度。瞬时速度被称为即时速度。它可以测量公式美元mathrm {V = | | =: |博士/ dt |} $。
平均速度与以前的不同,它指的是总距离由一个对象在一个特定的时间。
转速是指对象的数量,在一个特定的时间单位。
切向速度是指物体移动的速度沿着圆形路径(伊万诺夫et al . 2019年)。这个速度的公式是美元mathrm{切向速度:=:旋转速度:*:径向:距离:或者:v: =: rω:}$ v指的是切向速度,r代表转速和美元mathrm{ω}$指的径向距离。其他类型的速度是均匀和非均匀速度。
Different types of velocity
讨论了对象的运动速度有助于计算对象的运动方向和速度的基础上。它被定义为一个矢量,说明这两个方向和速度。以下是速度−下面列出的类型
恒定速度−材料以恒定速度不会改变方向或速度。唯一的材料,符合在连续旋转速度是那些把直线在最高速度(Sauerheber,McCallum, 2020)。材料在太阳系外宇宙空间不是外部力量的影响。
改变速度−转型对象的速度和加速度计算。材料与改变方向和连续速度加快(科学,2022)。小行星和彗星在太阳系内的对象的实例转换速度自方向或者速度是受重力的影响。
Figure 3: Motion graphs for velocity, acceleration and position
上面的图片代表运动的故事年代对象。位置,物体的加速度和速度一直画类似的间隔时间,每一个图形的形状与可预见的和特殊的方式。
−即时速度是迅速的过程演示材料正在改变其方向或速度在一个特定的时间点。理解是最小化时间利用计算加速度几量对象时不会移动。
终端速度−它基本上是用来讨论对象年代运动在空中自由下降。对象的下降到地面在真空中会不断加速,直到他们指出在地上。物体在空中的下降可能会停止运动,因为空气的阻力的上升(Lanzilao,迈耶斯,2022)。某点的空气阻力等于重力引起的速度定义为终端速度。
Difference between Speed and Velocity
Speed | Velocity |
---|---|
It is a Scalar quantity | It is a vector quantity |
It is described as a change of distance rate. | It is illustrated as the change displacement rate. |
It measures quantitatively how rapidly anything is shifting. | It illustrates the movement direction of an object or body |
No possibipty of obtaining a negative value | Possibipty of getting Zero. |
It is a prime indicator of object rapidity. | It indicates position with object rapidity. |

Conclusion
速度计算是一个极其重要的利用机械物理。通常表示为矢量对象的速度旅行在一个特定的方向。标量术语定义了绝对的速度矢量的大小说明了运动的速度。速度是由对象的距离在一个特定的时间无论旅行距离。定向组件的缺乏是一个标量。计算速度是容易所需的总路程除以总时间旅行。
