If youre given the components of a vector such as (3 4) you can convert it easily to the magnitudeangle way of expressing vectors using trigonometry. For example take a look at the vector in the image. Suppose that youre given the coordinates of the end of the vector and want to find By Steven Holzner . In physics when you break a vector into its parts those parts are called its components. For example in the vector (4 1) the x-axis (horizontal) component is 4 and the y-axis (vertical) component is 1.Check Your Understanding. 1. To test your understanding of this distinction consider the following quantities listed below. Categorize each quantity as being either a vector or a scalar.

A study of motion will involve the introduction of a variety of quantities that are used to describe the physical world. Examples of such quantities include distance displacement speed velocity acceleration force mass momentum energy work power etc.This vector addition calculator can add up to 10 vectors at once. DIRECTION must be entered in degrees increasing counterclockwise. In rather unscientific terminology a vector pointing directly to the right has a direction of zero degrees.In physics the Poynting vector represents the directional energy flux (the energy transfer per unit area per unit time) of an electromagnetic field.

Notice that the dot product of two vectors is a number and not a vector. For 3 dimensional vectors we define the dot product similarlyIn geometry a normal is an object such as a line or vector that is perpendicular to a given object. For example in two dimensions the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point.Introduction In this lesson we will examine a combination of vectors known as the cross product. Vector components in 3 dimensions will be combined in such a way as to result in another vector
