Velocity - math word problems - page 36 of 50
The velocity of an object is the time rate of change of its position. Velocity is a specification of an object's speed and direction of motion (e.g. 20 m/s to the south).In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position) - scalar.
