Science Toy VII (U shaped Track)

This is a real simple build, just bending angle iron around a 10” pipe. It is very effective at teaching Potential Kinetic Energy - Conservation of Momentum and Energy "lost to Friction". Attached Images

Reply:ThanksIf you are a famer you could teach me physics. My grandpa new more science than I could hope to.
Reply:Physics is really the quantification of what we know from experience by doing, and observing.  But it creates a model to predict(this is the biggy) the outcome of something we haven't experienced directly.  Engineering is, I guess, a prime example.  Structures can be built with some confidence that they won't collapse.  It's pretty cool stuff."Any day above ground is a good day"http://www.farmersamm.com/

Reply:Thanks Naudi2UWe are luck we have two good math teachers for the 8th grade. All kinds of hands on stuff. I'm glade I went to school in the 70's (The era of low expectations) todays math is a bitch. The eight graders do stuff we did as Jr/Sr.Have a good new years.
