Hello! I'm a little confused about some of the equations Professor Lavelle wrote on his whiteboard during the lecture at minute 38:35. From what I understand, p(momentum)=m(mass)*v(velocity). Below that equation he had on the board, Professor Lavelle wrote "E=pc." I'm confused about this because I thought velocity was doubled here, since velocity is part of the "p" in the equation and "c" itself is the velocity of light. If anybody could clarify/explain this for me, I'd really appreciate it! Thank you in advance!
He was trying to show all the other equations you could derive from E=m*c^2. This is similar to the equations we used in the photoelectric effect and how we would use what is given to us to answer a problem. Depending on what we are given, we can form different types of equations.
