2.1 Transfer of Energy Monday, January 18, 2021 13:42 Transfer of Energy Example: Let's consider a more complicated example. Transfer of energy Example : Simple Energy Flow: «» We will generally not consider the detailed mechanisms for how energy 1s transferred . Example: Santa Applied force: Work done on box ---> Kinetic Energy from one type to another. This guy starts from rest and pushes a box across the floor until he 1s «» We will consider the flow of energy during moving quickly. different processes. e ‘.’ The amount of detail included will depend on the situation being considered and what we want to learn/consider. “, Starts at the top with 0 Kinetic energy. Then gain some when he's at the bottom. More Complete Energy Flow: Where does this energy comes from? Potential energy when he's at the top decreases when he arrives at the bottom. This energy transfers to a kinetic energy. m = Energy Flow Energy can be transformed from one type to another. —_— — In the previous example gravitational potential energy was turned into kinetic energy. — In a situation we can track the transfer of energy from one type to another. — There can be many energy transfers
