Who is invented in kinematics?

Answer 1

Well obviously the person that was invented in kinematics is the massless, omniscient observer that calmly puts all the objects into motion instantaneously without consideration for past history or all other objects in the universe.

If the question had been "Who invented kinematics?". Well, really there is no one answer for that. Since kinematics is the study of motion and objects, humans have been doing that since the beginning of time. But who really started to scientifically analyze and put these observations onto paper? One of the most famous observer had been Galileo, who conducted many of the same experiments that physics students love doing experiments on. For instance, he observed that balls rolling down ramps traveled intervals of squared proportions (1, 4, 9, etc.) and he extrapolated that this held true for free falling objects too (though harder to observer without the technology of Photography). Another famous experiment was the pendulum experiment, in which he measured rather accurately the periods of pendulums of various size and length, and observed many of the fundamental consequences that we take for granted (i.e. period of a pendulum is independent of weight and amplitude). But what really set in stone the study of kinematics was the work done by Newton, which introduced mechanics (or force analysis), and Calculus (yes, yes, Leibniz too) and kinematics became a relatively well defined field of physics.
