What is velocity?

Velocity is a physical term that is defined as the rate at which an object changes its position in a given amount of time. It is a vector quantity, meaning it has both magnitude and direction. The SI unit for velocity is meters per second (m/s). Velocity can be calculated by dividing the displacement of an object by the time taken, or by differentiating the object’s position with respect to time. It is an important concept in physics, as it is used to describe motion, and can be used to measure the speed and direction of objects. In addition, the velocity of an object can change due to a change in speed or direction, which is referred to as acceleration.
