Eric Roner's Crazy Lawn Chair Balloon Flight Explaining Motion Eric Roner's Crazy Lawn Chair Balloon Flight

Erik on his Chair – Moving Up Q: Why does he go up? Beginning of flight 1:45

Erik on his Chair – Going Down Q: Why does he go down? Beginning of fall 3:22

Eric falls out of the chair 3:30 Erik Separates from his Chair Q: Why does he fall faster than the chair? Eric falls out of the chair 3:30

Erik Releases his Parachute Q: Why does he slow down? Parachute open 3:50

Things we need to know P1 Why does helium make things go up? What is air resistance? Why does Eric fall slower with the parachute than if he didn’t have it? What about the parachute slows him down? What is air pressure? What kind of gun did he use? Why did the balloons pop as they got higher and higher? Why does the number of balloons effect how high he goes? Does the number of balloons effect how high he can go?

Things we need to know P3 What is air pressure? While the helium balloons are popping, is Eric accelerating or does he reach a final speed? Did the chair fall to the ground before Eric or is it the other way around? What were the environmental conditions/factors – how much wind, etc? Why did Eric stop moving when he hit 8000 ft? What was Eric shooting with? How did Eric’s body react to the freefall? What was the difference in speed between the free fall and the fall with parachute? Did the number of balloons determine how high Eric could go? What is air resistance? Why did Eric do this in the first place?
