Velocity Notes
• What is velocity?
• How is velocity
measured?
• How does velocity
show both speed
and direction?
• A car is traveling
from L.A. to San
Francisco (1200 km
in 10 hours). What
is car’s velocity?
• Velocity is speed (Dist/Time) in a
given direction (N,S,E,W).
• Velocity is measured in units like
m/sec W or km/hr NE.
• A car traveling from BHMS to
Tijuana (80 km in 1 hour) would
have a velocity of 80 km/hr S.
• How are
velocities
combined?
(draw picture)
• If two velocities are in the
same direction they are added
together.
WIND =
10 km/hr West
Current =
5 km/hr West
Total
Velocity =
15 km/hr
West
• How are
velocities in
opposite
directions
combined?
(draw picture)
• If velocities are in the opposite
direction they are subtracted.
WIND =
10 km/hr West
Total
Velocity =
5 km/hr
West
Current =
5 km/hr East

Summary
• Write the shortest summary you can that
uses the following words:
• Velocity, speed, direction, km/hr East,
same, opposite, add, subtract,.
