So there's this guys argument that newtons 3rd law is wrong: "When I say that for every action there CAN'T be an equal an opposite reaction, it is a FACT. It's mathematically IMPOSSIBLE to have an EQUAL reaction to every action. Because then NO action would succeed. ALL actions would be right away countered by equal reaction! No action would be possible. Newton was 300 years ago. His ideas were revolutionary at that time, but like most great people he missed several points. Pawel" And here you can see videos of him basically saying the same thing: http://www.youtube.com/watch?v=X2cis7-SpmY&feature=channel_page http://www.youtube.com/watch?v=xi1y4MHK1N0&feature=channel I can see his mistake very well, but i'm not that good at English to explain it to him, so i want you guys to help me. Explain him his mistake as good as you can and i'll try to enlighten him :D... It MUST be a really good explanation because he's a complete dumbass - i mean, he thinks Earth is stationary...lmfao Scary... O_O Explain, why Newton's third law of motion IS correct.
