No it ' s not like that at all . There are impulses involved . It ' s more like jumping off the windshield towards the backseat . As you jump the car will actually move forward , until you hit the backseat and transfer your energy back to the car . So the car is actually expected to move forward , except it shouldn ' t move forward by that much . So people are arguing it is possible that you simply never hit the backseat with the same force , not only that but reflecting back and forth amplifies the force . Since photons are massless and relativistic it ' s possible that there is some extra trick here . <| sep |> Har aldrig sjlv haft problem med det , dremot var jag p en Smash Brosturnering ganska nyligen . Killen jag spelade mot satt och vaggade fram och tillbaka under hela matchen och skrek ut God fucking damn iiiiit i den gnlligaste rst jag ngonsin hrt . Efter att jag vann slet han i kontrollen och sa whatever , you roll way too much , so fucking easy . Jvligt obekvmt att spela med sdana .
