FOR BEGINNERS BY THE Wi REV. J. B. LOCK, M.A. SENIOR FELLOW, ASSISTANT TUTOR AND LECTURER IN MATHEMATICS AND PHYSICS OF GONVILLE AND CAIUS COLLEGE; FORMERLY MASTER AT ETON. 乙 London: MACMILLAN AND CO. AND NEW YORK. 1887 [All Rights reserved.] THIS work has been written in the hope of supplying a want which I believe is very widely felt; viz. of a book which explains the elementary principles of Dynamics, illustrating them by numerous easy numerical examples in a manner suitable for use in Schools with boys of ordinary mathematical attain ments. I have adopted a suggestion,-due I believe to Mr Hayward, F.R.S., of Harrow School-that the first part of the book should treat exclusively of Linear Dynamics; thus avoiding, at the beginning of the subject, all purely geometrical difficulties. It will be found that, with the exception of one or two Articles, Sections I. and IV. (which may be read separately, and in which the fundamental Principles of Dynamics are explained) demand only a knowledge of Simple Equations in Algebra. In no case is any greater knowledge on the part of the Student assumed, than is denoted by Progressions in Algebra, the Trigonometry of one Angle, and (in Chapters IX. and X.) the Parabola. I have ventured to suggest names for the units of velocity and acceleration, the use of which will be found to simplify considerably the language of the subject. I should be greatly obliged to those who may make use of the book if they would point out any defects or obscurities in the text or would offer suggestions for its improvement.
