Document Summary
G, m, k, d, c, m, u, n. If there are 6 cookies in a box, then: (6 cookies)/(1 box)=1 or (1 box)/(6 cookies)=1. Mass, time, distance, any vectors magnitude, etc. Vectors in 2 or 3-d space may be represented by their. Components their displacement in each coordinate direction. Vectors may be written in unit vector notation . R =38. 63 km x -22. 2 km y . Represent the total amount of movement during a displacement. Or, just the magnitude of the displacement. Velocity is the rate of change of displacement. Velocity is non-zero whenever displacement changes either. Change in position over the whole time interval. Or, the velocity at any given moment. If the velocity is constant , these two are equal. Change in velocity over the whole time interval. The limit as t goes to zero. Or, the acceleration at any given moment. If the acceleration is constant , these two are equal.
