Q19CQ - College Physics (Urone)

Question

What is the last thing you should do when solving a problem? Explain.

Step-by-Step Solution

Answer

After solving the problem, the last thing to do is to check that the answer matches the real-life situation.

Step 1: Consider whether the answer is feasible in the actual world

Examine the solution to see whether it is reasonable: Does this make sense to you. Because the goal of physics is to describe nature accurately, the last step is crucial.

Check the answer's magnitude and sign, and the units, to see if it's realistic.

As you solve many physics problems, your reasoning will develop, and you will be capable of making extremely good judgments about whether a solution accurately depicts nature.

Step 2: Is the Answer sensible? Check

The problem is reintroduced to its fundamental conceptual meaning at this level.

If you can assess whether the answer is reasonable, you have a deeper understanding of physics than simply being able to solve a problem mechanically.

These are the few steps that should be followed while solving numerical problems.
