1/2mv2 newtonian or non newtonian?

Question

Nobody woiuld ask if mm'/d2 or f=ma is a newtonian formula because it obviously is. So, when the same question is asked about 1/2 mv2,there is a possibility that the formula is not newtonian. In fac it was formulated by Leibnitz. Ask "Marquise du Châtelet" through google and you'll have a complete answer. Wouldn't it be right to give additionnal points to somebhaving posed a question followed by a wrong answer rewarded with the maximum of points?

Answer 1

The phrase "Newtonian" is, in general, referring to the type of physics you're dealing with (physica dynamics and kinetics), versus something from electromagnetism or relativity. And as far as whether Newton gets credit or not, keep in mind two things:

1. F = m a = m dv/dt = m d^2x / dt^2
2. Newton invented calculus.

E = 1/2 mv^2 is just integrating f = ma twice with respect to time.

Answer 2

Newtonian, I'd say, in the sense it was derived from Newton's physics, even if Newton himself didn't discover the formula.

For example, there would also be a derived formula that governs how high a roller coaster must go before it can complete a loop on its own. I'd call this formula Newtonian though Newton is unlikely to have contemplated it.

Though, it would be good in books to give credit where credit is due.

Answer 3

Liquid "cleansing soap" is probable newtonian. Non-newtonian fluids in lots of cases have suspended solids in them. Ketchup (or is it catsup?) is between the main acknowledged non-newtonian fluids - you probable attempt it each and every time you pour from a bottle.

Answer 4

Newton and Leibnitz invented Calculus at almost the same time. Newton invented differential calculus and Leibnitz invented integral calculus.

'Newtonian Dynamics', 'Hamiltonian Dynamics', Ls Grangian Dynamics', and 'D'Lamberts Principal' are all derived from Newtons basic Laws. The choice of which one to use rests on your choice of inertial reference frame and how badly you feel like beating yourself up

very much Newtonian

Umm...ok
