1. What 2 forces act on objects moving through the Earth's atmosphere? air resistance rain gravity rain air resistance gravity 2. A falling object _when the force of air resistance becomes equal to the gravitational force on the object. speeds up slows down continues at the same speed 3. Air resistance acts in the _ direction to weight same opposite 4. What is terminal velocity? What is terminal velocity? And how to get there quickly Click on the link to watch terminal velocity in action. Answer #5-7 5. The plastic space shuttle has _ air resistance than the wood board with handles. more less the same amount of 6. When the force of gravity is _ the force of air resistance this is called terminal velocity. less than greater than equal to 7. When the parachute of a skydiver is opened the air resistance _ increases decreases remains the same 8. Why is a sky diver falling not considered free fall? 9. Why are objects in outer space in free fall? 10. Remember back to the video from last week... The feathers the bowling ball were in free fall. True False 11. Objects in space are weightless. True False 12. The planets stay in orbit around the sun because of free fall. True False 13. Look at Figure 12 and explain what orbiting is. 14. A projectile motion has two parts ... vertical horizontal up down left right 15. The horizontal motion causes the ball to move _ and the vertical motion due to gravity causes it to move _ resulting in a curved path. backward; down forward; down forward; up 16. Why do you always aim high when shooting arrows at a target?
