The Uniform Velocity Motion.

This is a motion during which the instantaneous velocity is always constant.
Hence acceleration is zero.

	(1)
	(2)

A constant velocity reveals that:
1)the direction of motion is along a straight line.
2)Average velocity and instantaneous velocity have the same magnitude

By coupling the last relationship with the definition of average velocity, we can build the motion law for all the uniform velocity motions.



If  then , and the last relationship can be written as

As this law shows, the distance versus time graph is a straight line and its angular coefficient is the speed of motion
