Today we all went driving around Kailua and stopped over at this place to eat ramen. While waiting for our order, I noticed that there were a bunch of lanterns and decorations hanging all over the place and figured they might have something to do with the things that we learned about forces. Since the hangings were at rest (due to the lack of wind outside and inside the restaurant), the basic forces on the hangings were their weight and the normal forces holding them up to the ceiling. Since the heart hanging inside was at rest, the net force must be 0N. This would mean that the weight of it (its mass x gravity) must be equal to its normal force. This is from Newton's first and second laws, for an object at rest must have a net force of 0N and for every force, there must be an equal and opposite force.Monday, October 8, 2007

I honestly see things hanging, especially when there is more than one wire/string supporting the object, and think about this very thing. So good for you, too!
