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

It was such as amazing session! And you are super sweet and your explanations are spot on. The questions were also very well chosen. The session couldn't have been better. Im really excited for the next session.

Thank you for this session on force and translational dynamics! I learned a lot about force as a vector, including different kinds of forces (e.g., contact vs field) and friction (static vs kinetic). Moreover, I learned about the normal force, which is the surface force perpendicular to the surface of interaction between two objects. I really like how you broke down the vocabulary with illustrations, and the practice problems were easier to follow through because of your patience and creative ways of explaining! In addition to illustrations, you also showed an example on camera with a diary in contact with another object. I look forward to the next sessions! :)

Thank you for this informative session! I really enjoyed doing the practice problems and learning when to use the right kinematic equations. I also enjoyed the interactive simulation of velocity and acceleration when you were sharing your screen. It was fun launching the piano! :)

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! 🤓

Thank you for this session! I learned a lot about applying the different concepts of physics, including acceleration, net forces, contact forces, frictional forces, coefficient, and more. I really enjoy solving problems with the diagrams using mgsin(theta) and mgcos(theta)! 💯

Thank you for the practice AP level problems!

Learner · 4 mo. ago

Thank you! The formula derivations were confusing but you simplified it in a way that I can understand! Definitely recommend this tutor!

Thank you for this session! As a beginner in AP Physics 1, I am glad to find this helpful series! You’re very kind and explain the different concepts very well such as scalar quantities, vector quantities, speed, velocity, displacement, and acceleration. I learned a lot in my first session. I look forward to the upcoming sessions, and I will do the homework for extra reinforcement! Thank you! :)

Thank you so much for hositng this session! You had a really interactive lesson and were so patient to! It really helped that you kinda covered some basics along with the new - I needed that memory refresh. :)
