TEDx Topic
For TEDx or DVCx my group was Jalen, Pearl, and I. Our topic was friction and to show what friction is we used a sander on a piece of wood that we painted as we used the sander on the wood it scraped to paint off, dented the wood, and created some heat. The definition of Friction is: Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
