10-12

Today we reviewed Newton's 1st and 2nd laws of motion and added a bit of understanding / depth with how F=m*a    applies to mass, weight, and gravity.  Notes were given according to this outline and we had some additional inertia demonstrations. 
Tomorrow we'll spend some time looking over exams and right/wrong answers and any arguments for points, and try to quantify (verify with numbers) Newton's 2nd law (F=ma).
Maybe we'll get to a discussion on why I claim all objects on Earth are accelerated at -9.81 m/s/s due to gravity, and why mass doesn't make a difference.
