maybe positive or negative. Therefore the termacceleration includes retardation as well :is increase in ve-locity. Retardation is negative acceleration. If the particle moves in a straight path with :i velocitywhich increases or diminishes at a constant rate it- accel-eration equals, numerically,… … 90 ANALYTICAL MECHANICS Since vi and v2 are in the same line, their difference will be avector in the same direction. Therefore in this particularcase the acceleration is constant not only in magnitude butalso in direction. The following definition of acceleration is general andholds true whatever…
