text: Galileo was instrumental in describing the characteristics of falling objects by determining that the acceleration of every object in free-fall was constant and independent of the mass of the object.
text: Weightlessness does not occur when a spacecraft is firing its engines or when re-entering the atmosphere, even if the resultant acceleration is constant.
text: T, his equation, however, only works for constant forces (that is, when acceleration is constant for situations in which mass does not change).
