Fig. 5. 12. The component acceleration in a specified direction is theacceleration of the corresponding component velocity. 13. When the acceleration varies in magnitude, or direction,or both, and a velocity AB Rt P (Fig. 6) becomes ^C at ^ in time t. then — approximates more and more closely to… … Fig. 6. 14. If the unit of time be changed from 1 second to t seconds,the numerical value of the acceleration will be changed from/to ff^ . ELEMENTARY MECHANICS.
