Another wonderful question, from yours truly..
if you have one tonne, moving at 3klms per hour, what is the potential energy? in kw?
uuummm? dont even know whether it is a valid question?
be great to get some feedback.
cheers

It has no potential energy in the purist sense unless it's on a hill with the brakes on. It has kinetic energy k = 0.5 x m x v x v (half m v squared) m = mass, v = velocity (speed in the wb's case assuming it is going in a straight line). If it's going ar |

Hi fallingbear.
There will be lots of noughts because the velocity is squared, i.e. 3,000m/s x 3,000m/s. (Then multiply this by 3,600 x 3,600 to convert seconds to hours) This results in 116.64 x 12 noughts. If you then multiply it by 1000 (kg) x 0.5, |
If at first you don't succeed, just call it Version 1.0 |

hey thanks dr terry,
11.6 cubic metres, is the average amount of water flowing down the murray, taken across its width and depth.? I just felt it was easier to just use 1 cubic metre, to estimate the potential?
now this madness all started, cause i am |
