Why can perpetual motion not exist if newtons 3rd law implies it can?
In a nutshell, Newton’s laws are: 1. Objects at rest stay at rest and objects in motion stay in motion with the same speed and direction, unless the object is acted upon by a force. 2. Force = Mass * Acceleration 3. For every action there is an equal and opposite reaction. Perpetual Motion is loosely defined as “getting as much energy out of a system as you put in”. Of course, the ultimate Perpetual Motion machine gives you MORE energy than you put in. A Perpetual Motion machine would solve the world’s energy problems forever (if one existed). Newton’s third law does specify an EQUAL reaction. However much energy you put into a system, exactly that much energy must come out. Unfortunately, you have to account for everything in the equation and part of everything is friction. You can’t escape friction. Even in the darkest recesses of intergalactic space, there are a minimal number of particles that will eventually slow you down. No energy conversion process can give you 100% of the outp
