Velocity & Direction
Focus on the man walking across this page.

The answer depends on your coordinate system. The man is moving to the north (or up, forward, y) and the east (or across, to the right, x). Since his easterly displacement is greater, he has a greater easterly velocity
Ex) Joe drove 13 meters North East in 2.0 seconds What was Joes ...
Ex) Joe drove 13 meters North East in 2.0 seconds We can say that Joe has 3 velocities V = 6.5 m/s N.E.
V = 5 m N/2 seconds =
2.5 m/s North
V = 12 m East/2seconds = 6 m/s East
1. Velocity is always written with direction
Examples
• 5m/s east
• 100 m/s downward
• -100 m/s
2. Equation:
V = ∆d/∆t
d = displacement V = ∆d/∆t
V = (50. m N)/(20. sec)
v = 2.5 m/s North
