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 Current = 5 km/hr East Total Velocity = 5 km/hr West
