  London, UK (The Conversation) Dec 11, 2019 Some landslides on Mars seem to defy an important law of physics. "Long, runout landslides" are formed by huge volumes of rock and soil moving downslope, largely due to the force of gravity. But their power is hard to account for. With volumes exceeding that of the Empire State Building, they move at high speeds of up to 360 kilometres per hour over flat surfaces for up to tens of kilometres. This seems to indicate that there is no or very little friction present. Friction is the fundamental physi ... read more |
