In physics class, there is a lot of physics, almost every day. When Mr. Fullerton drinks his coffee, the coffee is being acted upon by an outside force. Gravity helps get the coffee out of his Dunkin' cup and into his mouth. Also, Mr. Fullerton doesn't drink his coffee with any "pollutants." The normal physics of stirring in creamer and sugar doesn't apply to this case. The coffee that Mr. Fullerton relies on to be able to deal with students like me in the morning has a lot to do with physics because of all the forces acting upon it. There is also friction between his hand and his cup. without this, the cup would slip out of his hand and he wouldn't have any then. That would make Mr. Fullerton very angry.
