Key Concepts
- Newton's second law: F = ma
- Kinetic energy KE = ½mv²; potential energy PE = mgh
- Conservation of momentum in closed systems
- Ohm's law: V = IR for resistive circuits
- Always attach SI units: kg, m, s, N, J, W
Common Mistakes
- Mixing grams with kilograms in formulas
- Forgetting to square velocity in kinetic energy
- Using degrees in formulas requiring radians
- Ignoring vector direction in momentum problems
Frequently Asked Questions
Prefer SI units: kilograms, meters, seconds, newtons, joules. Convert before calculating.
Yes — it depends on v². Direction does not affect KE magnitude.
