What CAUSES motion?
Kinematics describes motion.For constant acceleration, we have found that
Dynamics deals with the explantion of motionNow we will look at cause and effect.>> Why does something move?
>> Why does something CONTINUE to move?
>> What causes something to STOP once it is moving?
These are questions of Dynamics.
Sir Isaac Newton (1642 - 1727) built upon the ideas of Galileo. Newton's three Laws of Motion are general, universal LAWS that explain a wide range of situations.
(Newton also invented Calculus and made great contributions in Optics, including inventing the reflecting telescope).
