Velocity.
The length of the arrow signifies the magnitude or size of the vector.
In short, yes.
A vector.
A vector is represented graphically as an arrow. The direction indicates the direction, the length is proportional to the magnitude of the vector. Note that it is difficult to accurately represent vectors of 3 or more dimensions on a 2-dimensional sheet of paper.
Velocity.
The length of the arrow signifies the magnitude or size of the vector.
The length of a vector arrow represents the magnitude of the vector. It indicates the size or amount of the quantity being represented by the vector.
The vector shows the direction and magnitude of motion of an object. The direction is represented by the direction of the vector arrow, and the magnitude is represented by the length of the vector.
The length of a vector arrow represents the magnitude or size of the vector. It indicates how much of a quantity is being represented by the vector in a given direction.
In short, yes.
A vector.
Vectors can be represented on a diagram by drawing an arrow from a reference point (origin) to the final point of the vector. The length of the arrow represents the magnitude of the vector, and the direction of the arrow indicates the direction of the vector in space. Additionally, sometimes vectors are represented by bold letters or with a line segment over the variable symbol.
Vector quantities can be represented graphically by using arrows. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector. The starting point of the arrow can be placed at the origin of the coordinate system.
The beginning point of a vector is referred to as its origin or initial point. It is the starting position from which the vector is measured or represented by an arrow.
The symbol for a vector is typically represented by an arrow placed above the variable name or by using boldface type. For example, a vector quantity velocity "v" would be represented as a vector v or $\vec{v}$.
Magnitude of the force.
