Most students treat every physics problem as a brand-new puzzle. Strong students treat every problem the same way, using one repeatable process. Here's the exact framework we teach.
- 1. Draw it — sketch the situation before writing a single equation.
- 2. List knowns and unknowns — write every given value with correct units.
- 3. Name the concept — identify which law or principle actually applies.
- 4. Choose the equation — pick the formula that connects your knowns to your unknown.
- 5. Solve, then sanity-check — does the size and unit of your answer make physical sense?
Why step 5 matters most
The sanity check is the step almost every student skips — and it's the one that catches careless errors before they cost marks. If your answer says a car is moving at 4,000 m/s, something went wrong two steps earlier.
