Definition of the uniform linear motion
An object experiences uniform linear motion if the velocity of the object is constant. Velocity includes the magnitude and direction of velocity. Direction of velocity = direction of veguhestinê = direction of movement. The direction of the velocity of a constant object = the direction of motion of a constant object, or the direction of motion of a fixed object = the object is moving straight. The magnitude of velocity or speed is constant = the speed is always the same all the time.
