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
