HAND-HELD HELICOPTER
National Standard: B2
“... unbalanced forces will cause changes in the speed or direction of an object’s motion ...” 1
Suggested Use
Flight is the result of unbalanced forces. A blade’s shape or pitch can create lift. This hand-held device is a great way to demonstrate lift. Be sure to push your right hand forward, and left hand backward — otherwise the helicopter will go down instead of up! (Related concept: Bernoulli Principle)
