Sam used the internet to research the difference between reality and paradigm. She described how perception and reality are related. She continued to work on an assignment.
We started the session by going over his assigned homework that consisted of drawing force diagrams and finding the net force on an object. Corrections were made to the problems he got wrong and a thorough explanation was given. We reviewed vector analysis and the importance of finding the components of a vector before using any equations to find unknowns. We went back to the previous chapter on kinematics and reviewed some of the problems that include vector components of velocity or acceleration to demonstrate the similarity to working with forces.

Lesson Comments
Vlad was late to his session because he had to pick up his sister.
An introduction to forces was given. We went over some basic definitions, the units of force and an explanation of the four fundamental forces of nature and how any force can be broken down to originating from one of these four. We discussed Newton's three laws in relation to forces, how to draw force diagrams, and the method of finding the net force by summing over the various components.

Lesson Comments
Vlad had some issues with vector analysis and finding components of a vector (basic trigonometry) so I would like to work more with him on this before moving on. Because he said he had finished with the previous chapter on kinematics and did the problems and didn't have any issues with it, I started the session by jumping into the next chapter thinking he had understood all previous material. I think the next time I meet with him I should go back to the previous chapter and confirm that he has a thorough understanding of how to solve kinematics problems.
I gave Vlad the practice test on two-dimensional motion including projectiles launched at angles and horizontally, motion through moving fluids, relative motion, and resultant vectors from component vectors. I gave him help where needed and we finished the practice test. There was no assignment.

Lesson Comments
Vlad has some trouble with basic trigonometry, which I would not expect to see in an Advanced Placement Physics student. He also is having trouble choosing the correct formulas to use in some basic calculations.
Vlad and I reviewed the homework problems and continued on with some other problems including projectile motion launched horizontally and at an angle, relative motion, motion in a moving fluid, and motion on different headings with component and resultant vectors. There was no assignment.

Vlad did not do the homework because he was stressed by his weekend golf tournament.
Projectiles launched at an angle and releative motion
Lesson Outline
I checked Vlad's homework which was two problems on projectiles launched at an angle. He got the first one right and I helped him with the second one. I then introduced moving frames of reference, which is a tool used to analyze motion. We did some problems together to reinforce this idea and I gave him some problems from the end of the chapter to do in class and for homework.

Lesson Comments
Vlad is working hard to learn the correct problem solving procedures.
I worked with Vlad to solve two problems where objects were launched at angles with varying velocities and from varying heights. Vlad had to read the problems, make sketches, list the information he was given with the correct variable names, select appropriate equations, and solve them. These were extremely difficult problems. His assignment was to do the next two problems of this topic.

Lesson Comments
Vlad is working herd but he is trying to guess too much at the answer or the correct approach or equation without enough analysis first.
Projectile motion of objects launched horizontally
Lesson Outline
I explained to Vlad how horizontal motion and vertical motion operate independently of each other and that to find the position of a horizontally launched projectile, resolve the components of the velocity vector. The vertical component must use acceleration due to gravity and the horizontal component must use constant velocity. The assignment was to read pages 99 and 100 about projectiles launched at an angle.

Lesson Comments
Vlad was able to follow the example shown and to do all of the problems associated with horizontally launched projectiles.
Vlad and I discussed an applied physics problem he is working on and then reviewed the homework problem. The idea was to add two vectors algebraically when each was the resultant of perpendicular vectors. We finished the problem and I guided him through finding resultant velocities for perpendicular velocities. The assignment was to read p.95-99 about projectile motion.

Lesson Comments
From time to time, Vlad makes some errors in the mathematics required in physics. For now, I am forcing him to apply the math so that he will learn it.
I explained how two vectors which are each composed of components can be added together to form a resultant. I showed Vlad that each vector could be resolved into its components and the components with the same direction could be added together. After all components in each direction are combined, They are used to form a single resultant vector whose magnitude and direction can be found using the Pythagorean theorem and the inverse tangent function. I assigned Vlad to do one problem to review this process.
