Lets Play Around With Two Big Ideas in Physics. Itll Be Fun
b'The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, which often leads students to think they are similar. In a way, they are, and they play a huge role in almost everything you learn during an introduction to physics. Before I give you a great physics question that uses these ideas, I will go over them in a super-brief physics lesson.\\nLearn more about your ad choices. Visit podcastchoices.com/adchoices'
