With forces, interaction diagrams and Newton’s second law we now have in hand all the tools needed to tackle a mechanics problem: we know how to classify the forces in play, identify them without forgetting or inventing any, and translate them into accelerations via . The next chapter puts these tools to the test on two particularly important applications — the inclined plane and circular motion — while later, in the chapter devoted to energy, we will introduce an alternative and often more powerful method: the energy method, based on energy exchange diagrams, the “energy” analogue of the interaction diagrams we have learnt to build here.
