Work and Energy
Manage episode 435185710 series 2770060
In this episode, we cover the topic of work and energy. We’ll start off by talking about work, which includes the mathematical and conceptual definitions and the sign convention of work. We’ll also talk a little bit about mechanical advantage and also path dependency. Moving on to energy, we’ll talk about the general definition of energy, we’ll compare and contrast energy in work and the different types of energy that includes kinetic energy, potential energy, thermal energy, and total mechanical energy. Lastly, we’ll talk about energy transfer, specifically heat transfer, and the three types of convection, conduction, and radiation.
