What is velocity?

Answer

Velocity is a vector quantity that describes the rate of change of position of an object and the direction of motion.

Solution

Definition of Velocity: Velocity is defined as the displacement (change in position) of an object divided by the time during which the displacement occurs. It is a vector quantity, which means it has both magnitude and direction. The mathematical expression for velocity,

\vec{v}

, is given by

\vec{v} = \frac{\Delta \vec{x}}{\Delta t}

, where

\Delta \vec{x}

is the displacement vector and

\Delta t

is the time interval

Key Concept

Velocity as a Vector Quantity

Explanation

Velocity not only tells us how fast an object is moving but also in which direction it is moving.
