Usually the first one is right and the second is up.
The velocity vector of an object that is speeding up to the right points in the same direction, to the right. Velocity is a vector quantity that includes both magnitude (speed) and direction, so as the object accelerates, the velocity vector will align with the direction of motion.
Any vector can be "decomposed" into components along any two non-parallel directions. In particular, a vector may be decomposed along a pair (more in higher dimensional spaces) of orthogonal directions. Orthogonal means at right angles and so you have the original vector split up into components that are at right angles to each other - for example, along the x-axis and the y-axis. These components are the rectangular components of the original vector. The reason for doing this is that vectors acting at right angles to one another do not affect one another.
The orthonormal is a direction at right angles to the vector.
If one component of vector A is zero along the direction of vector B, it means the two vectors are orthogonal or perpendicular to each other. Their directions would be such that they are at a right angle to each other.
Vector quantities have both magnitude and direction I think u can also look it up on Google for a more in depth answer but this is basicaly right Yeaya Whos da bomb ....not you!
decomposition of a vector into its components is called resolution of vector
When vectors are added together, the result is still a vector.Here's a way of looking at it: Person A (vector A) walks one mile north, and Person B (vector B) walks two miles east. If a different person, Person C (vector C, the result of adding vectors A and B) did both, Person C would walk one mile north then two miles east. Since the shortest distance between two points if a line, you can draw a path from where you started to where you ended up after both vectors.If you drew these three vectors (one unit up, two units right, and the resulting vector), with one original vector's end point at the other vector's start point, and a third vector leading from the start point of the first to the end point of the second, you should see a triangle.This can also be applied to the addition of more than two vectors.
A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
The shortest distance from start to finish.
Vectors are added graphically tip to tail. You subtract vector B from vector A by adding vector -B to vector A. Where -B means a vector that points in the opposite direction as B , but has same magnitude. For example to subtract B (magnitude 4, points left) from vector A (magnitude 3, points up), first draw A, then draw -B (magnitude 4, points right) ,starting -B at the tip of A. Then the vector that connects the tail of A to the tip of -B is the difference A - B or A + (-B) . In this example A & -B form the legs 3 & 4 of a right triangle so the hypotenuse (which is A - B) is 5.
It's a vector one.
Oh, dude, okay, so like, a resultant vector is the overall effect of two or more vectors combined, while a component vector is just one of the vectors that make up the resultant. It's like saying the whole pizza is the resultant, and the pepperoni and cheese slices are the component vectors. So, basically, the resultant is the big picture, and the components are just the pieces that make it up.
