How to practise physics.
- 1
Draw it first
A quick sketch of the forces, the circuit or the ray path shows what is happening before you touch a formula.
- 2
Write the units on every line
If the units on both sides do not match, the working is wrong. It is the fastest check there is.
- 3
Check the direction and the sign
Many lost marks are a minus sign or a wrong direction. Say which way is positive before you start.
- 4
Estimate before you calculate
Ask if the answer is the right size. A car that takes 0.002 seconds to stop should make you look again.
- 5
Learn the few big laws properly
Newton's laws, energy conservation and Ohm's law explain most of a paper. Know when each one applies.
- 6
Redo your mistakes after a week
Repeat the questions you got wrong after a few days. That is when a method either sticks or fades.
Questions, answered.
- Is the physics practice really free?
