Help in Study: Physics — How to Stop Drowning in Formulas
May 8, 2026 · 7 min · help in study physics · physics help AI · physics formulas
Most students fail physics for one reason. They memorise formulas instead of memorising what each formula is for.
Look at any past paper. Each question is a tiny scenario asking, "which physics situation is this?" If you spot the situation in five seconds, you know which formula to reach for. The math becomes the easy part.
The question filter
When you read a question, ask in this order:
- Is something moving? → kinematics
- Is energy changing form? → work / energy / power
- Is there a force? → Newton's laws
- Is electricity involved? → circuits, fields, induction
- Is light or sound involved? → waves
- Is heat involved? → thermal physics
Most A-Level / IB / FSc / IGCSE questions sit cleanly in one of these.
Build a one-page identity card per topic
For each topic write:
- The two or three formulas that matter
- A single sentence about when each applies
- The one classic trap question
- A worked example
Formula Sheet generates this for your board. Print it. Tape it to your desk.
Past papers, every weekend
Past papers are not about memorising answers. They are about pattern recognition for the question filter above. Use Past Papers every weekend. After ten weekends you have seen almost every type of question your board uses.
Common pitfalls
- Mixing up scalar and vector quantities. Speed and velocity are not the same.
- Wrong units. Always check the unit on the answer line.
- Forgetting g = 9.81 m/s² or 10 m/s² depending on what the paper specifies.
- Treating derivations as memorisation. They are stories. Each line follows from the one above.
