Velocity

In physics, velocity is defined as the speed and direction in which an object moves.
It is a vector quantity and has both magnitude (speed) and direction.
The SI unit of velocity is the *meter per second* (m/s).
In the example above, "60 miles per hour" is a speed (a scalar quantity), whereas "north at 60 miles per hour" is a velocity (a vector quantity).

What happens when the direction or speed of a moving object changes? It is called acceleration, which is the rate of change of velocity.

People could talk about velocity without knowing it.

You actually specify a velocity when you say, "I am driving up north at 60 miles per hour."
