SUMMARY
Simplifying assumptions are not strictly required in physics problems, but they are often necessary to arrive at a solution when critical parameters are missing. For instance, in problems involving free-fall, neglecting air resistance simplifies calculations without significantly affecting accuracy for small distances. The discussion highlights that while assumptions may lead to approximate solutions, they are essential for modeling real-world scenarios, as seen in examples from Giancoli Physics 6e. Ultimately, the necessity of these assumptions stems from the complexity of real-life physics, where not all variables can be accounted for.
