Velocity, in physics, is a vector q

Velocity, in physics, is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of an object). However, quite often when you read 'velocity', what is meant is speed, the magnitude of the velocity vector (speed is a scalar quantity, it has only magnitude). For example: escape velocity (the minimum speed an object needs to escape from a planet, say); note that this can be easily turned into a velocity, by adding 'in the direction radially out from the center of the planet', and that this direction is sometimes implied (if not actually stated).
