Thank you for hosting this awesome session on work, energy, and power! I learned a lot about conservative forces. Any system which loses energy is non-conservative force (e.g., air resistance). Potential energy is the energy of the object which has potential to move. Kinetic energy is the energy of the object in motion. I really enjoyed deriving how the maximum velocity = √2gL(1-cosθ) for a pendulum. At max height, all energy is potential: PE = mgh. At lowest point, all energy is kinetic: KE = 1/2(m)(v^2). Thank you for always teaching me how to approach every problem with diagram and interpreting variables before substituting into a kinematics equation! You're a gem in the Physics subworld on SchoolHouse! 💎

Thank you for this session! It was so fun solving the force and acceleration problems together using diagrams and deriving equations! I never taught AP-styled Physics questions can be so conceptual and enjoyable at the same time! :D

Thank you so much for hosting today's session on work, energy, and power! I learned so much about work, force, kinetic energy, and potential energy! I enjoyed learning calculus application in physics too. I really like how you explain the derivation of different formulas and emphasize drawing free-body diagrams. You're truly helping me to prepare for AP Physics 1 - a course that I barely knew anything about in previous years. 😇

Thank you for this awesome session! I learned a lot about pulleys & Atwood machine, elevators, normal force, apparent weight, and so much more! I didn’t realize how interesting the physics of elevators is! Next time I hop onto the elevator (tomorrow), I’ll definitely be thinking more critically! 🤓
