Notes on Accelerated Motion and Newton`s Laws
... required not only to start something moving but also to keep it moving. Much later, Galileo realized that, in fact, all bodies have a tendency to keep doing what they are doing, i.e. if at rest, they will tend to remain at rest, and if moving, they will tend to keep moving. This tendency is today re ...
