Can inertia be used as a force for propulsion?
In: 9
What you’re suggesting is basically how you play pool – you hit the white ball, and the white ball must hit the other balls to propel them into the holes. While it clearly works in pool, it is a rather violent method of getting things moving and a spaceship isn’t going to appreciate a launch by having something slam into it. The impact is just as likely to cause major structural damage as it is to make it move.
