The problem

You know the law, you pick the wrong unit, and the paper scores nothing.

The hard part of this subject is almost never understanding: it is the conversion, the forgotten subscript, the power of ten that slips. Those mistakes are not fixed by rereading the notes, they are fixed by being caught on them, often and briefly.

The quantity AND its unit

A card asking for an energy expects joules. Splitting the two means learning half of something you will be marked on in full.

Subscripts survive the copying

E subscript c, v squared, ten to the minus thirty-four: what always gets lost in hastily copied notes stays crisp inside the card.

Orders of magnitude settle through repetition

Knowing an electron weighs ten to the minus thirty kilograms is not intuitive. That kind of landmark only settles by being asked for again and again.

From your notes to cards

One mechanics chapter, three cards.

The notes become cards of three different shapes, each chosen for what it checks.

Uploaded excerpt · mechanics, energy

The kinetic energy of a body of mass m moving at speed v equals one half m v squared. Planck's constant is expressed in joule-seconds. A force applied to a mass gives it a proportional acceleration.

Formula

Kinetic energy of a body of mass m at speed v

E_{c}

in joules, with m in kilograms and v in metres per second

\frac{1}{2} m v^{2}

Two-sided

In what unit is Planck's constant expressed?

The joule-second (J·s).

Multiple choice

A 10 N force acts on a 2 kg mass. What acceleration?

5 m/s²

20 m/s²

0.2 m/s²

10 m/s²

The right shapes

What genuinely gets checked in physics

Three shapes are enough, provided you use them where they bite.

Formula

It carries subscripts and exponents without flattening them, which no keyboard entry can guarantee.

Two-sided

Ideal for units and constants: a closed question and an answer that tolerates no approximation.

Multiple choice

Here the distractors are factors of ten and inversions — exactly the slips made under exam conditions.

Frequently asked questions

Do subscripts and exponents come through correctly?

Yes, because the notation is typeset rather than entered as plain text. A squared velocity shows as squared, a subscript stays a subscript, and a negative power keeps its sign.

Can I revise circuit diagrams?

A question can carry an image, so a labelled diagram works: components are hidden and you name them. For a circuit to be built, the card carries the principle, not the drawing to redo.

How should I work on unit conversions?

With very short, very numerous cards, revisited briefly. A conversion is a reflex, and a reflex is built by how often it is recalled rather than by how long you sit with it.

What about a lab report?

It yields excellent protocol cards: the order of the steps, the role of each measurement, the precautions. Those are precisely the questions asked in an oral.
