Holding the end of a rope on which a heavy object is being swung around at constant speed in a circle does not transfer energy to the object, because the force is toward the centre of the circle at a right angle to the displacement. No work is done in either case. The mathematical expression for work depends upon the particular circumstances.

Speed versus Velocity

Speed versus Velocity

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is a directionaware quantity. The average velocity is the displacement (a vector quantity) per time ratio.
