I saw here on Wikipedia that if the speed you're working with is less than 10% the speed of light, Newtonian Mechanics are still accurate. So, my question is: If you are working with a speed that is less than 10% the speed of light, then will all Newtonian Mechanics variables and equations still hold true? Also, what does it mean on that page by "within a margin of error of 1%"? Does it mean that if you are working with a speed that is 10% the speed of light, then your Newtonian Mechanics calculation will be accurate to within 1% of your figures? What if you are working with a speed that is 5% the speed of light - is the margin of error still 1%? Or, by margin of error, does it mean that Newtonian Mechanics hold if your speed equal to, or below 10% the speed of light +/- 1% of the speed of light?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks,

Jake
