Velocity (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an "acceleration". To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed. For
What Is it Like to Be a Bat? to have a conscious experience it must be special, in the sense that its qualia or "subjective character of experience" are unique. Nagel stated, "An organism has conscious mental states if and only if there is something that it is like to be that organism – something that it is like for the organism to be itself."

A subjective character of experience cannot be explained by a system of functional or intentional states. Consciousness cannot be explained without the subjective character
