Vector

In mathematics and physics, a 'vector' refers to a quantity defined by both magnitude and direction, making it distinct from a scalar, which has only magnitude. Vectors are used to represent physical quantities such as force, velocity, and acceleration. In computer science, vectors also denote dynamic arrays that can change size. The term originates from Latin, meaning 'to carry.'

Vector meaning with examples

• In physics, an object’s motion can be fully described by a vector indicating its speed and direction. For instance, if a car travels north at 60 km/h, the speed represents its magnitude, and the northward direction completes the vector description of its movement.
• A vector depicting the gravitational force exerted on an object shows both the strength of the force and its direction toward the center of the Earth. This dual aspect is crucial for understanding how objects interact under gravitational influence and is widely applied in physics to solve problems.
• In computer graphics, vectors are utilized to define shapes and movements. For example, when designing a video game character, one might use vectors to determine the character's position and the direction in which it is facing, allowing for realistic animations and interactions within the game environment.
• In biology, vectors can refer to organisms that carry pathogens from one host to another, such as mosquitoes transmitting malaria. Understanding these vectors helps in controlling disease spread and implementing effective public health interventions.
