WebHow do rockets work in space. I don’t know if this is the best subreddit to post this question in, but if there is no air to push against in space how the hell do rockets work? The exhaust gasses are pushing against the back of the nozzle. Rockets, contrary to airplanes, helicopters, etc., don't need air to press against. WebHeat is driven by temperature differences, while work involves a force exerted through a distance. Nevertheless, heat and work can produce identical results. For example, both can cause a temperature increase. Heat transfers energy into a system, such as when the sun warms the air in a bicycle tire and increases the air’s temperature.
