What special properties does an atmosphere confer to a swing?
- gpderetta 7y agoMaybe they meant in 0g?
- dean177 7y agoYou need “downwards” acceleration for a swing. The vacuum bit isn’t important, it’s the gravity. They probably meant 0g rather than vacuum.
- SSLy 7y agonone, but centers of gravity do
- labawi 7y agoIt slows you down :) The vacuum part was an emphasis on requiring a counterpart to change momentum. In an atmosphere you could flap your wings, or use electric fans, and argue what it means to ride a swing, but it would be besides the point, as in an atmosphere there is no need for propellant-less engines from the article.
