uk 3 SPIN ME ROUND A fascinating example of early engineering first seen in Roman Egypt, this steam-powered aeolipile works by the expulsion of steam through nozzles, generating thrust according to the rocket principle and Newton's Second Law of Motion.

CONCLUSION We have shown crucial steps in the derivation of the equation of motion of yarn: the introduction of the non-uniformly rotating obsrvation frame, the calculation of velocity and acceleration and the application of Newton's second law to an infinitesimal segment of yarn.

Besides the difference in metaphysics, the alternative to Newton's second law given by equation (26) offers an advantage in resolving some philosophical issues regarding the foundations of Classical Mechanics and in particular the need to consider fictitious forces when applying Newton's Second Law in non-inertial reference frames.

Renowned for riding into fence, hitting fence hard, and not coming off, thereby disproving Newton's second law of gravity (or it might be his first?

Gramer, Gornitz and Weizsacker use Newton's second law as an example.
