1. Two birds perched directly next to each other, leave the same tree at the same time. They both fly at 10 km/h for one hour, 15 km/h for 30 minutes, and 5 km/h for one hour. Why don’t they end up at the same destination?

2. 1. What is velocity? 1. A vector quantity (measured in both magnitude and direction) 2. The rate of change of position in a given direction 3. is considered constant when speed and direction do not change 4. changes as speed or direction changes 5. can be combined (added if moving in the same direction and subtracted if moving in the opposite direction)

3. 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

4. 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

5. Why do rockets take off in the same direction as the earth’s rotation?

6. Why does it take less time to fly from California to New York than to go from NY to California? JET STREAM

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