Geometric representations of magnitude and direction
- Vectors are geometric representations of magnitude and direction which are often represented by straight arrows, starting at one point on a coordinate axis and ending at a different point. All vectors have a length, called the magnitude, which represents some quality of interest so that the vector may be compared to another vector.

Most commonly in physics, vectors are used to represent displacement, velocity, and acceleration. Vectors are a combination of magnitude and direction, and are drawn as arrows. The length represents the magnitude and the direction of that quantity is the direction in which the vector is pointing.

Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity.
- Is it still a vector if we say "The brick moved 5m towards Sal" even if 'towards Sal' has no specifi...As you told towards Sal means you have given a specific direction as Sal is standing in a specific direction so it is a vector quantity

A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down. The direction of a vector in one-dimensional motion is given simply by a plus (+) ( +) or minus (−) ( −) sign. Vectors are represented graphically by arrows.
Apr 23, 2019 · A vector quantity is defined as the physical quantity that has both directions as well as magnitude. A vector with a value of magnitude equal to one is called a unit vector and is represented by a lowercase alphabet with a “hat” circumflex, i.e. “û“.
