What CAUSES motion?

Kinematics describes motion.

We have already described one-dimensional motion,

and two-dimensional motion,

Dynamics deals with the explantion of motion
Now 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).
