slim Posted May 29, 2007 Share Posted May 29, 2007 Hi Simon, There are lots of reasons why a direct comparison doesn't work but because we all live on planet Earth we can make a conversion. Gravity is a force pulling down (no, really) with a force of 9.81N per Kg. So your 120N force would lift 12.2Kg straight up. Although it wouldn't really, it would just make it appear weightless. To make it move you'd need to add a little more force. Another way of looking at it is Newton's Force=Mass x Acceleration equation (Newton's second law) applied to a pilot and motor etc with a total mass of 200Kg: 120 = 200 x A A=120/200 A=0.6m/s/s Or, with a force of 120N behind him, assuming no wind resistance or lift or anything else (ha ha) our pilot will experience an acceleration of 0.6 meters per second per second. Or for each second his speed will increase by 0.6 meters per second. Or, for each second that passes his speed will increase by 2.16Km/hour which is roughly equivalent to a 0 - 60 time of 44.5 seconds. Just for reference, the force of gravity acting on our pilot should he collapse his wing would cause an acceleration of 9.81m/s/s which is equivalent to a 0 to 60mph time of 9.76seconds. As clear as mud? Thus endeth today's lesson. Stuart Quote Link to comment Share on other sites More sharing options...
