Big Ideas Of Science
This program simulation the motions of a boat and a walker. Initially, a walker (weigh Ma=50 kg) is standing still (Va=0) on a boat (weight :Mb)。There is no external force act on this system, there is no friction between the boat and water surface when the boat moves either. When the simulation is played, the walker starts to walk at a constant speed Va. Do you know how fast will the boat move correspondingly?
此程式模擬一不受外力的作用的船上載著一個人，假設船與水面間無磨擦力，當人以等速 V 移動向船緣移動時，人與船的運動。人重50公斤(Ma)，船身重Mb公斤，船身全長為20公尺。
