If youve been following these videos from the beginning, you may see a pattern emergingwe learned the basics, applied the basics to forces, applied forces to energy, and now its time to apply energy to this next section. Power is the rate at which energy is used (or converted, as per the conservation of energy law). Mathematically, power is simply the time derivative of the change in energy (most of the time problems will be straightforward with having something constant, such as velocity). Power is a relatively small topic as its just like learning velocity right after learning about displacement, which allows us to move onto another big topic in mechanics.
Power is the rate at which work is performed, or the rate at which a force does work.
Units of power are Joules/second, known as Watts.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
