💡 Essential Physics Calculation Tips
📐 Unit Consistency
- ✓Always verify unit compatibility before calculations
- ✓Use SI units (meters, kilograms, seconds) as standard
- ✓Convert all units before starting calculations
- ✓Check dimensional analysis for equation validity
- ✓Double-check prefix conversions (k, M, G, m, μ, n)
🔢 Significant Figures
- ✓Follow sig fig rules precisely in all calculations
- ✓Consider measurement uncertainty and error propagation
- ✓Round final answers appropriately (not intermediate steps)
- ✓Maintain precision throughout multi-step calculations
- ✓Use scientific notation for very large/small numbers
🧠 Problem Solving Strategy
- ✓Draw free-body diagrams and visual representations
- ✓Identify all known and unknown variables clearly
- ✓Choose appropriate physics equations for the scenario
- ✓Verify results match physics intuition and reality
- ✓Check limiting cases and order of magnitude estimates
💡 Physicist's Tip: Always start with a clear diagram and coordinate system. Write down all given information and what you're solving for. Use energy methods when possible - they often simplify complex mechanics problems. For electricity problems, Kirchhoff's laws are your best friend. When stuck, check if conservation laws (energy, momentum, charge) apply!
