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
