Unit 2 Section 4 Notes Newton`s Laws of Motion
... Astronauts in space appear to be “weightless”. This statement is NOT true because gravity exists everywhere in the universe; it is the force of attraction between 2 objects due to mass. Astronauts in orbit experience apparent weightlessness because they are in free fall. The astronauts and vehicle ...
