Velocity is a vector quantity that describes the rate of change of an object's position with respect to time, including both speed and direction. It is represented mathematically as $\mathbf{v} = \frac{d\mathbf{x}}{dt}$.
5 Must Know Facts For Your Next Test
Velocity has both magnitude (speed) and direction, making it a vector quantity.
The SI unit for velocity is meters per second (m/s).
In two-dimensional kinematics, velocity can be broken down into components along the x and y axes: $v_x$ and $v_y$.
Addition of velocities follows vector addition rules, meaning you must consider both magnitudes and directions.
Relative velocity involves finding the velocity of one object as observed from another moving object.
