Recent Tutoring Session Reviews
"I began with momentum and collision. We compared the momentum of a 5 gram bullet, a 100 gram arrow, a 100 kilogram football player and a 15,000,000 kilogram ship. For my "ship blown into the dock" problem, the boys were able to calculate the rate of closure of the ship with the pier, given an acceleration of only 2 mm/second square. So at least they are able now to combine F=ma with a problem relating to collision time. Further, we began talking about kinetic energy and conservation of momentum, using the classic ice skater type of example. They wanted to begin talking about work and machines, but we pretty much stopped after getting to W=Fs and a discussion of how the World's Laziest Man can use physics to get work done with no expenditure of force!"
"The student and I went through practice problems on gas stoichiometry for his upcoming quiz. There were a couple bumps but for the most part he is mastering the material."
"The student and I continued to cover one of his problem sets that mostly involved molecular and net ionic equations, oxidation number, and solubility. He had an innately good understanding of oxidation number from the beginning, which will be helpful in further topics. We also began talking about acids and bases. Overall, it was both productive and a fun session."
