In physics, velocity is the rate of change of position with time unit the unit is meters per second (m/s) in unit vector quantity velocity, which consists of speed and direction.
In physics, velocity is the rate of change of position per unit time. In meters per second (m / s) in the International System of Units is the velocity vector, which contains the speed and direction.
In physics, the speed is the rate of change of position of per unit time is measured in meters per second (M / s) in the international system of units (SI), speed is a vector quantity, which consists of speed and direction.
