Velocity example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration. Speed describes only how fast an object is moving, whereas velocity gives both how fast it is and in which direction the object is moving. If a car is said to travel at 60 km/h, its speed has been specified. However, if the car is said to move at 60 km/h to the north, its velocity has now been specified.
Love Must Be Tough to Rock 'n Roll)". In October 2008 "Love Must Be Tough" was named Record of the Year by Hi-Fi+ Magazine. "It's an even year, so it must be an Eleanor McEvoy album that's up for an award. Following in the footsteps of "Yola" and "Out There", this year's offering from the Irish chanteuse, "Love Must Be Tough", excels even the exalted standards set by its predecessors. What started out as a collection of covers, songs she wanted to sing from a woman's perspective, rather than in their more normal male voice, soon grew into something more - much, much more."
