25.3 Relativistic Velocity, Momentum, and Energy | General Physics

Chad provides a lesson on Relativistic Velocity, Momentum, and Energy. The lesson begins with a review of relative velocity from a Galilean perspective. But an object's relative velocity cannot exceed the speed of light, and for objects with velocities approaching the speed of light, relativistic effects must be factored in using an equation often termed the Relativistic Addition of Velocities. This equation is introduced with the variables all defined and then used in solving an example problem.
Momentum and energy from a relativistic perspective are presented next. Once again, for objects with speeds approaching the speed of light, the classical definitions of momentum and energy are not sufficient and their more complex relativistic counterparts are used. The relativistic formulas for total energy, rest energy (E=mc^2), and kinetic energy are presented along with mass-energy equivalence. The rest energy of an electron is calculated to conclude the lesson.

Hey Chad, I see in your physics master course that chapters 21.3-21.6, 22.2-22.5, and 23.3-23.8 were all removed in your "Updated Physics Video Series" and in the course. Do you know why they are no longer taught in your new curriculum, and if you will make updated videos for those chapter sections, or will we have to only look back at your old videos?
Furthermore, do you know if you if it would be possible for you to cover Chapters 27 (Quantum Physics), Chapter 28 (Atomic Physics), and Chapter 29 (Nuclear Physics) in College Physics 2? Thank you so much in advance!

Hi Annabella! I restructured the curriculum a little bit. Instead of several shorter lessons, I combined all of the material in chapter 21 into just 2 longer lessons. I also combined all the chapter 22 lessons into a single long lesson (it was just more cohesive) and then moved the lesson on the polarization of light to the end of chapter 24. Next, I have combined the curriculum for Quantum Physics and Atomic Physics into a single chapter which will be released this week. Lastly, I had not planned to produce a chapter on Nuclear Physics, but I'll give it some more thought. Happy studying!
