Vector A vector is defined as a physical quantity that contains a certain magnitude with a sense of direction. If the direction of a vector is changed, then this becomes a new vector. The addition of two vectors is done by t...
Velocity is often used interchangeably with the scalar quantity of speed, but the two terms have distinct differences. Speed measures the distance traveled per unit of time and ignores the direction traveled. Velocity, however, is a vector quantity that considers change in position over time (magni...
Knowing the vector perpendicular to a plane is important in many applications, such as in physics and engineering. It can be used to calculate the direction of force or motion on an object, determine the angle of incidence and reflection of light, and find the shortest distance from...
