The Student and Tutor reviewed key concepts in thermochemistry, including definitions of endothermic and exothermic reactions, enthalpy change calculations, and methods for representing these changes. They discussed the energy involved in bond breaking and formation, as well as examples of each type of reaction. The session aimed to prepare the Student for an upcoming test.

Student and Tutor reviewed key concepts of Uniform Circular Motion, including angular displacement, angular velocity, and centripetal force and acceleration. They practiced applying these concepts through various real-world examples, such as a car on a banked road and a car in a vertical loop. The session also covered Newton's Laws in the context of circular motion and the calculation of work done.

The Tutor introduced the Student to Year 2 Physics, focusing on circular motion concepts including centripetal force, angular displacement, and angular speed. They covered definitions, units, and the conversion between radians and degrees, deriving key formulas. The Student is expected to send their formula sheet, and the next session will involve algebra-based problems and vertical circular motion.

The Student and Tutor reviewed concepts of relative motion, including scenarios with moving frames of reference, and then moved on to projectile motion. They practiced solving problems involving boats crossing rivers and projectiles launched at angles and horizontally, including calculating velocity components, time of flight, and range. The next lessons were scheduled for Wednesday and Saturday evenings to cover remaining topics before the Student's upcoming exams.

The Student reviewed notes on the photoelectric effect, atomic spectra, and wave-particle duality with the Tutor. They explored electron diffraction experiments, the De Broglie wavelength, and the principles of laser production, specifically stimulated emission. The Tutor planned to continue the discussion on laser systems in the next session.

The Tutor and Student reviewed the photoelectric effect, focusing on graphical representations of intensity, potential, and frequency versus photoelectric current. They also discussed atomic absorption and emission spectra, linking them to energy level transitions and associated photon energies, and planned to cover wave-particle duality in the next session.
