Family Dinner


So on Sunday night, my uncle, auntie, and two cousins came over for dinner. It was just an average, normal family dinner. But then I saw that my two cousins (both girls, 5 and 7 year's old) had a new toy with them. It was one of those barbie/fairy doll flying spinners, and instantly I thought "OH YEAH, physics blog" So to work these toys, a large amount of force is required to pull on a cord, which will cause the toy fairy to spin rapidly, and fly into the air. I realized that part of this motion involved centripetal acceleration and centripetal force, similar to the homework problems we have been doing in class. So anyways, I watched my cousins play with their toys after dinner and studied the motion of the toy after it launched. I noticed that this motion seemed like a parabola, and perhaps may deal with kinetic equations, except for the fact that the toy was spinning in the air. Maybe someday later I'll learn how that affects flight motion. (something like that picture up top, but in a barbie/toy model)
