"Student has started learning about Ohm's law. We worked on her homework for the week and she did really well with it. Solving for voltage, current, and resistance was really easy for her. When we moved on to circuits and adding resistors in parallel and in series, she completely understood how to do it. After physics, we worked on geometry for a little bit and she had to do a study guide about circles, arc, chords, tangents, and secants. She almost never has problems with geometry and tonight she continued to breeze through all of the problems. She is still doing really well in her classes and does not seem to be having much trouble with the material in either physics or geometry."
"The student worked on an assignment that had her calculate the amount of energy eaten per day when consuming 3 burritos. Then she converted this rate to other units of power and the energy consume to other units of energy including horsepower, watts, kilowatt hours, ergs, electron Volts. She also converted the rate per to day to rate per year and compare the cost of eating 3 burritos per day versus the cost of consuming the equivalent amount of energy in gasoline or electricity. She is very diligent setting up the dimensional analysis and completing the conversions."
"Today we talked about the science of the movie Interstellar, mostly universal gravitation. I walked the student through how Newton arrived at his law of universal gravitation and how that law is used to find the orbits of planets and stars. We also talked about experimentation in science and physics and how the accepted truths of physics has changed over time starting with the introduction of Newton's laws, Relativity, and Quantum Mechanics. We spoke a little about units and measurement, significant digits and scientific notation. Her curiosity about physics makes her an excellent student."
"We went over her math packet for her upcoming exam, and we focused mostly on word problems and unit conversions. We worked out how to translate what is being asked in the math problem using the same technique as the physics words problems. We covered how to identify the unknown and list the know variables, find the appropriate equation and then plug in the numbers. Her biggest struggle is identifying which equation to use, but once she has seen as example she is able to apply the same method. She is improving at finding similar examples that she had done previously in class and applying either the same method or modifying the method slightly. At times she takes a little longer to make the connection but improves with practice."
"We went through Kinematics problem. Student had brought his own questions for practice. I explained the problems without skipping any steps. Students seemed to have understood the problems we went through."
"We went through several problems on momentum, collisions, impulse, and center of mass. We talked about how to find the center of mass of a system by taking the sum of each mass multiplied by their coordinates, and then dividing by the total mass. We also looked at the integral formulas for center of mass in each of the coordinate directions. We went through the two different formulas for impulse and practiced calculating the impulse of an impact. We also talked about how the average force of an impact changes with the amount of time the impact takes using the examples of catching a baseball or an egg with your bare hands. We practiced sketching collision problems to show the 'before' and 'after' momentums, including the 'inelastic collision' where a single object breaks apart into multiple objects. The student is doing well setting up the momentum equations for a collision problem, and she is doing better calculating impulse and 'explosive collisions.'"
