SB Ch4D1 Acc.notebook 1 Relative Motion Relative Motion Calculate velocities of objects when viewed from various f.o.r. Objective: Compare motion using frames of reference Motion A change in position relative to some reference point during a period of time. Frame of Reference - background in which to analyze motion - assume Earth is the f.o.r. - motion of a f.o.r. cannot be detected w/o another f.o.r. to compare it to Relative Velocity - velocity compared to a specific f.o.r. 10 mi/hr 30 mi/hr Relative Velocity - velocity relative to ....... 10 mi/hr 30 mi/hr 30 mi/hr Assignments . . .
