Most people would just assume there's some grain and maybe a little sugar, or a lot of sugar if you're more of a Lucky Charms person than a Raisin Bran person. Nobody would suspect, though, that there would be metal in their Cheerios. Turns out, Cheerios are magnetic. Or are they?
Fill a bowl with water and drop in a couple Cheerios. Take a magnet and hold it just above the Cheerios, the Cheerio will be attracted toward the direction of the magnet. Why is this? If the little cereal ring is magnetic, then there must be metal fragments in it causing the attraction. Now the cereal is all magnetic, and it does contain tiny fragment of iron. This is perfectly reasonable though, as iron is a key nutrient in a human diet. But that's not the whole story,
If you were to try this with objects other than cereal, say a small piece of paper or plastic, it would still seem to be attracted to the magnet as it floated in the water. The "attraction" you see is actually all about water, which is diamagnetic, meaning it generates a magnetic field opposite to that of the magnetic field it is in the presence of. Thus, the water is slightly repelled by the magnet. This causes a slight divot in the water, that the object in the bowl actually falls into, making it appear to follow the magnet. In actuality, it isn't being affected directly by the magnetic field, but by the waters reaction to the magnetic field.Wed, 05 Apr 2017 12:45:47 +0000The Physics of KSPSounds like you'll have a head start on our "post-AP" project!Wed, 05 Apr 2017 12:00:12 +0000An Physic CNot quite sure I understand what "Mr. Fullerton is for the boys" means, but glad to hear you've gotten something out of the course. I, too, am glad you've stuck with it. Couple more weeks of pushing and the finish line is in sight!Wed, 05 Apr 2017 11:57:07 +0000Twilight PhysicsI was right with you up to the part where you said "it isn't that horrible of a movie." The missus made me sit through it once. The post-viewing fever lasted three days.

As corny and goofy as the show is, what always impresses me is the quality of the writing... and I'm really enjoying the fact that my 7-year-old is now all about watching Doctor Who with her dad whenever mom isn't home (Mommy would find it 'inappropriate.')Wed, 05 Apr 2017 11:51:39 +0000AP Physics C Q3 OverviewSo thrilled you've enjoyed the course. Recognizing it's the most technically challenging (as well as highest workload), and coupling that with an exceedingly frustrating instructor who is happy to sit back and let you struggle, you've done a mighty nice job in stepping up to the challenge. Only a couple weeks left... don't let up!Wed, 05 Apr 2017 11:47:18 +0000Little Tiny PiecesYou're on the home stretch of a mighty difficult course, not just in content but also in terms of level of independence. You've done well -- keep it up for just a few more weeks!Wed, 05 Apr 2017 11:45:36 +0000The Physics of Moving On :(Sure been nice having you in here!Wed, 05 Apr 2017 11:38:16 +0000Physics of baseballhttp://aplusphysics.com/community/index.php?/blogs/entry/30916-physics-of-baseball/When a person swings a baseball bat and hit a ball with a wooden bat rather than a aluminum bat, it will generally not travel nearly as far. Why is this? This is a concept of momentum on the baseball field. The biggest reason for the ability for a person to hit a ball further with an aluminum bat is because when they do, they are able to swing the accelerate the bat to higher speeds than if they were to use a wooden bat. Momentum is directly proportional to velocity therefore the faster the swing of the bat the further the ball with travel in most cases.Wed, 05 Apr 2017 10:46:37 +0000
