I watched the "Helping Hand" episode of Love, Death & Robots on NetFlix, where the protagonist is adrift in space. Every second she is further from her ship, and when her tank is out of oxygen, she throws her glove to propel herself back to the ship.
But I don't know how propulsion works in zero gravity. She needs to throw something heavy to make this propulsion? If she throws something like her watch, will it have the same effect as if she throws her heavy suit gloves?
My question is, if you are in space, and you needs to change velocity, and you have something to throw, is it better to throw the heaviest thing?
