4.1.2.P14

One of the things we try to do in a physics course is to take everyday concepts, such as motion or force, and refine them into more precise terms; often splitting everyday concepts so as to allow a more specific description and the development of physical laws. One example is the dividing of the concept of “motion” into “velocity” and “acceleration.” For the concept of force discuss in what way the everyday concept of force is split in physics and discuss one example from this class where not paying attention to this split might cause confusion. Note: This is an essay question. Your answer will be judged not solely on its correctness, but for its depth, coherence, and clarity.
