That is often called the magnitude.
No. The size of the size of the vector drawn indicates the magnitude.
That all depends on the angles between the vector and the components. The only things you can say for sure are: -- none of the components can be greater than the size of the vector -- the sum of the squares of the components is equal to the square of the size of the vector
another displacement
It is a vector with the same magnitude (size) but acting in the opposite direction.
There does not seem to be an under vector room, but there is vector space. Vector space is a structure that is formed by a collection of vectors. This is a term in mathematics.
The vector size() member returns the current size of the vector, in elements.
The size of the velocity vector is the speed.
No. The size of the size of the vector drawn indicates the magnitude.
Particle size is another name for the term grain size.
Still another velocity vector (or a zero vector).
That all depends on the angles between the vector and the components. The only things you can say for sure are: -- none of the components can be greater than the size of the vector -- the sum of the squares of the components is equal to the square of the size of the vector
another displacement
The size of a vector is not fixed at time of compilation as it can be altered by events that can be written into code. For example, a vector can have a new Node pushed to the back when something happens, altering the size of the vector during run-time.
The term "speed" is commonly used to designate the magnitude of the velocity vector.
A vector.
It is a vector with the same magnitude (size) but acting in the opposite direction.
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
