Qualitative Velocity
M. Teresa Escrig, Francisco Javier Villalba Ruíz de Toledo · 2002
The concept of velocity of an object relates an interval of time with the space that this object has travelled in such interval of time. Velocity is always relative: we compare the distance that an object has travelled in a period of time with respect to the position of another object. Although velocity is a quantitative physical concept, we also need a qualitative model of velocity if we want to automatically reason in a human-like way. In this paper, a qualitative model for representing and reasoning with the concept of velocity has been introduced.
