If they are parallel, you can add them algebraically to get a resultant vector. Then you can resolve the resultant vector to obtain the vector components.
Graphically: By laying them head-to-tail (move one of the vectors without rotatint it, so that its tail coincides with the head of the other vector). Algebraically: Separate each vector into components, e.g. in 2 dimensions, separate it into components along the x-axis and along the y-axis. Add those components. To subtract, just add the opposite vector.
Spliting up of vector into its rectangular components is called resolution of vector
Ans :The Projections Of A Vector And Vector Components Can Be Equal If And Only If The Axes Are Perpendicular .
Velocity is a vector, you can sum velocity in terms of direction components such as x and y.
If they are parallel, you can add them algebraically to get a resultant vector. Then you can resolve the resultant vector to obtain the vector components.
To add vectors, add their corresponding components together. If the vectors are in 2D, add the x-components together and the y-components together. If they are in 3D, add the x, y, and z-components accordingly. This will result in a new vector representing the sum of the original vectors.
You can add vectors graphically (head-to-foot). Mathematically, you can add the individual components. For example, in two dimensions, separate the vector into x and y components, and add the x-component for both vectors; the same for the y-component.Here it may be useful to note that scientific calculator have a special function to convert from polar to rectangular coordinates, and vice-versa. If you RTFM (the calculator manual, in this case), it may help a lot - a vector may be given in polar coordinates (a length and an angle); using this special function on the calculator can do the conversion to rectangular (x- and y-components) really fast.
The result is a new displacement vector that is found by adding the components of the two original vectors.
Vectors are added by adding the components of each vector in the same direction. For example, to add two vectors in the x-direction, you add their x-components, and for the y-direction, you add their y-components. The resultant vector is then the sum of these component-wise additions.

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.
To add the x and y components of two vectors, you add the x components together to get the resultant x component, and then add the y components together to get the resultant y component. This gives you the sum vector of the two original vectors.
The components of a vector are magnitude and direction.
The components of a vector are magnitude and direction.
No, you cannot directly add two vector quantities unless they are of the same type (e.g., both displacement vectors or velocity vectors). Otherwise, vector addition requires breaking down the vectors into their components and adding corresponding components together.
To add vectors by rectangular components, simply add the corresponding components of each vector. For example, if vector A has components (Ax, Ay) and vector B has components (Bx, By), then the sum of the two vectors can be found by adding the x-components (Ax + Bx) and the y-components (Ay + By) to obtain the resultant vector.
