**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. Velocity Notes**How are velocities combined? (draw picture)**If two velocities are in the same direction they are added together. WIND = 10 km/hr West Total Velocity = 15 km/hr West Current = 5 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**Why do rockets take off in the same direction as the**earth’s rotation? Answer this Question**Why does it take less time to fly from California to New**York than to go from NY to California? Answer this Question JET STREAM**Summary**• Write the shortest summary you can that uses the following words: • Velocity, speed, direction, km/hr East, same, opposite, add, subtract,.
