Suppose the magnitude of the vector is V and its direction makes an angle A with the x-axis, then

the x component is V*Cos(A)

and the y component is V*Sin(A)

How do you find the vector components only given the magnitude and x-component?

If you assume the vector is only in two dimensions, you can find the missing y-component with Pythagoras' Theorem: y = square root of (magnitude2 - x2).


How do you find the components to a vector?

Given the vector in angle-radius form? y-component=r sin(theta), x-component=r cos(theta)


How do you find the component of a vector perpendicular to another vector?

The component of a vector x perpendicular to the vector y is x*y*sin(A) where A is the angle between the two vectors.


Why vector quantities cannot be added and subtracted like scalar quantities?

Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.


How will you get the resultant of all vectors?

Graphical Vector AdditionDraw your first vector. Then draw the tail (start) of your second vector at the tip (end) of your first vector. Then draw the tail of your third vector at the tip of you third vector (if it exists,) and so on. To find the resultant, draw a vector from the tail of the first vector to the tip of the last vector. The angle of the resultant will be between the resultant's tail and the first vector's tail. To find these values, it is recommended that you use a scale (e.g. 1cm:1m) and a protractor so that your values are accurate.Or, to do it mathematically (with 2 vectors):You have vector a with angle Ao, and vector b with angle Bo.To get vector c (resultant,) break the vectors up into their x and y components, then add the x and y components to find the x and y of the resultant. To find the magnitude of vector c, use Pythagoras's theorem, a2 + b2 = c2. To find the angle of c, use inverse tangent, tan-1(y/x)Example:Remember that sin = y and cos = x. Thus, to find the x component of a vector, use cos, and to find the y component of a vector, use sin.c = square root( (acosA + bcosB)2 + (asinA + bsinB)2 )angle of c = tan-1( (asinA + bsinB)/(bcosA + bcosB) )


What is the sum of two or more vectors added together called?

The sum of any number of vectors is itself a vector, just as the sum of any number of scalars (normal numbers) is a normal number.If a vector is resolved into 2 components, x and y, in the form [x,y], then it can be added to any other vector resolved into 2 components [z,a].[x,y]+[z,a]=[x+z,y+a]


Find the x and y components of vector 120 N at 40 degrees?

Read the theory part of your book before you ask these questions


What must you do to non-perpendicular vectors before you can use the Pythagorean theorem to calculate the resultant of the vectors?

You must find the x and y components of each vector. Then you add up the like x components and the like y components. Using your total x component and total y component you may then apply the pythagorean theorem.


How do you find the y-component of a vector if you are given x-component and z-component?

You don't. Knowing two of the vector's orthogonal components doesn't tell you what the third one is. It could be absolutely anything.


How a vector can be express in term of its rectangular component?

A vector can be represented in terms of its rectangular components for example : V= Ix + Jy + Kz I, J and K are the rectangular vector direction components and x, y and z are the scalar measures along the components.


How do velocities add together?

Velocity is a vector, you can sum velocity in terms of direction components such as x and y.


What is component method of vector vector addition?

Any vector could be resolved into perpendicular components one along x axis and the other along y axis. So all vectors would be split into two components. Now we can easily add the x components and y components. If all in the same simply addition. If some are in opposite we have to change its sign and add them. Finally we will have only two one along x and another along y. Now we can get the effective by using Pythagoras.
