Why (according to classical physics) do forces compose according to the parallelogram of forces? This question has been controversial; it is one episode in a longstanding, fundamental dispute ...

THE objection to Duchayla's proof of the “parallelogram of forces” is, I suppose, admitted by all mathematicians. To base the fundamental principle of the equilibrium of a particle on the ...

THIS book is one of a series of manuals now being published by Messrs. Cassell and Co., intended for the use of technical students, and claims, to quote the preface, “to put before non-mathematical ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...
