    Could an Object Bounce Forever in a Frictionless Environment?

    If anybody could prove this in other ways or point me to references it would be great. I am using this to prove to a somwhat stuburn teacher of mine that either doesn't understand what he is teaching or more likely is just not listening / thinking about what I said. Just a logical statement that...

    Testing Battery Energy: Questions and Answers

    If u could calculate one or a few batteries and map out its voltage as time passes you could make a table / equation and then be able to calculate the expected life left of other batteries with equal expected ratings. There are equations / tables out there for this kind of thing relating types...

    I have a physics question that’s puzzling me. If say there was theoretical environments were there was absolutely no friction, but have a large solid celestial body that exerted significant gravity and there was an object that was perfectly elastic. If this object were dropped at say 10 meters...
