TEST BANK FOR An Elementary Treatise on the Dynamics of A particle By S L Loney Converted

FUNDAMENTAL DEFINITIONS AND PRINCIPLES 1. The velocity of a point is the rate of its displacement, so that, if P be its position at time t and Q that at time t +4t; the limiting value of the quantity PQ 4t , as 4t is made very small, is its velocity. Since a displacement has both magnitude and direction, the velocity possesses both also; the latter can therefore be represented in magnitude and direction by a straight line, and is hence called a vector quantity. 2. A point may have tw...
