YOU DON'T NEED TO STUDY PHYSICS FOR 5 HOURS A DAY TO GET BETTER AT IT. YOU NEED 30 MINUTES OF THE RIGHT KIND OF STUDY.

One thing I have noticed from years of teaching Physics is that many students confuse long hours of reading with effective learning.

A student can sit with a Physics textbook for three hours, read page after page, underline almost everything, and still struggle to solve a simple question the next day.

Meanwhile, another student studies for just 30 minutes—but studies actively—and makes far better progress.

The difference is not always intelligence.

It is the method.

If you have only 30 minutes each day for Physics, this is how I recommend using it.

THE FIRST 10 MINUTES: UNDERSTAND ONE CONCEPT

Don't try to cover an entire topic.

Pick one small concept.

For example, if you're studying acceleration, don't simply memorize the formula.

Ask yourself:

What is acceleration?

What does it mean when acceleration is positive or negative?

How is acceleration different from velocity?

What happens to acceleration when velocity changes?

Connect the idea to something real—a car speeding up, slowing down, or changing direction.

Your goal here is understanding, not memorisation.

THE NEXT 10 MINUTES: SOLVE QUESTIONS

Now close your textbook.

Take 2–4 questions related to what you just studied.

Try them yourself.

Don't immediately look at the solution when you get stuck.

Ask:

What information has been given?

What am I expected to find?

Which Physics principle connects the two?

This is where many students begin to develop real Physics ability.

Reading shows you what somebody else knows.

Solving shows you what YOU know.

THE LAST 10 MINUTES: CORRECT AND REFLECT

Now check your answers.

If you made a mistake, don't simply erase it and copy the correct answer.

Find out why you made the mistake.

Was it:

- A wrong formula?
- Poor understanding of the concept?
- A unit error?
- A mathematical mistake?
- Misreading the question?
- Substituting the values incorrectly?

Write down the mistake and the lesson you learned from it.

This small habit is incredibly powerful.

Because your mistakes become part of your learning process instead of something you simply hide.

And here's something I want every Physics student to understand:

You don't become good at Physics by studying only when an examination is approaching.

Physics is a skill.

Skills improve through consistent practice.

Thirty focused minutes every day can be more valuable than five unfocused hours once a week.

You don't need to finish an entire textbook today.

You need to understand one concept better than you understood it yesterday.

Then another tomorrow.

And another the next day.

After several weeks, those small improvements begin to compound.

So if Physics has been giving you problems, don't start by saying:

"I need to study Physics for 5 hours today."

Start with:

"For the next 30 minutes, I am going to study Physics properly."

That's a much better place to begin.

UNDERSTAND → SOLVE → CORRECT → REPEAT.

Do that consistently, and you will be surprised at how much your Physics can improve.

If you're a Physics student, save this post and try the 30-minute routine today.

Then come back and tell me: Which part of Physics are you currently struggling with?

STOP READING PHYSICS LIKE A FORMULA SHEET. START READING IT LIKE A STORY.

One of the biggest mistakes I see students make when studying Physics is this:

They open their textbook, see a formula, copy it into their notebook, memorize it, and move to the next one.

Then the examination comes.

The question is presented differently.

Suddenly, the formula they memorized seems to have disappeared from their memory.

Why?

Because they learned the formula, but they never learned the story behind the formula.

After years of teaching Physics, I have learned that students understand Physics much faster when they stop treating it as a collection of equations and start asking:

What is happening here?

Take motion, for example.

Don't begin with a formula.

Imagine a car leaving a school gate.

It starts slowly. Then the driver presses the accelerator. The car gains speed. After some time, the driver applies the brakes and the car slows down.

That simple story is already teaching you about velocity, acceleration and deceleration.

Now the formulas have meaning.

The same thing applies to forces.

Don't just memorize Newton's laws.

Imagine pushing a heavy box across the classroom.

You push harder, but the box barely moves.

Why?

What forces are acting on it?

What happens when your applied force becomes greater than the opposing forces?

Now you're not just memorizing Newton's laws.

You're thinking like a physicist.

This is how I encourage my students to approach every Physics topic:

1. Start with the situation.
What is happening in real life?

2. Identify the Physics.
What concept explains what you're seeing?

3. Understand the relationship.
How are the quantities connected?

4. Then learn the formula.
Now the equation becomes a shortcut for something you already understand.

5. Finally, solve questions.
This is where understanding becomes skill.

A formula without understanding is something you can easily forget.

But when you understand the story behind the formula, the formula becomes much easier to remember—and much harder to misuse.

So the next time you sit down to study Physics, don't immediately ask:

"Which formula should I memorize?"

Ask:

"What is happening here, and why?"

That question can completely change the way you learn Physics.

Physics is not a formula sheet. Physics is a story about how nature behaves. Learn the story, and the formulas begin to make sense.

If this is something a Physics student needs to hear, tag them in the comments.

And if you're preparing for WAEC or another Physics examination, comment "UNDERSTAND FIRST". Let's see how many students are ready to change the way they study Physics.

YOU GOT THE ANSWER WRONG... BECAUSE OF UNITS.

I’ve watched students do almost everything correctly in a Physics calculation—identify the right formula, substitute the values, calculate carefully—and still lose marks at the end.

The culprit?

Units.

A student sees 5 cm and writes it directly into a formula that requires metres.

Another calculates a quantity correctly but gives the answer in the wrong unit.

Someone else writes km/h when the question requires m/s.

These may look like small mistakes, but in Physics, they can completely change your answer.

This is why I constantly remind my students:

Numbers alone do not tell the whole story. Units tell you what those numbers represent.

Before you substitute values into a formula, ask:

👉 Are my quantities in the correct units?
👉 Do I need to convert anything?
👉 What unit should my final answer have?

Don't wait until the end to check.

Make units part of your solution from the beginning.

Because in Physics, a correct number with the wrong unit is not a complete answer.

Master your units, and you’ll eliminate one of the easiest ways to lose marks.

UNDERSTANDING BEGINS WHEN YOU SEE IT IN REAL LIFE.

One thing I’ve learned from years of teaching Physics is that students understand concepts differently when they can connect them to something they already experience.

You can spend 30 minutes explaining pressure on a board.

But place a sharp nail beside a blunt one and ask:

“Which one enters wood more easily—and why?”

Suddenly, the concept becomes real.

That is the power of connecting Physics to everyday life.

When a student feels the resistance of a rough surface, they begin to understand friction.

When they watch a ball fall, gravity stops being just a definition.

When they see a rainbow, light dispersion becomes more than a diagram in a textbook.

When they use a bottle opener, a door handle, or even a wheelbarrow, they are already experiencing simple machines.

This is why I tell my students:

Don't just memorize what Physics says. Look for where Physics is happening around you.

Because the moment you can connect a concept to something you have actually seen, touched, or experienced, understanding becomes much deeper.

The classroom should not be the place where Physics starts and ends.

The real laboratory is all around you.

Look carefully.

Physics is happening right in front of you.

IF YOU CAN'T PICTURE IT, YOU CAN'T SOLVE IT.

One thing I’ve noticed when teaching Physics is that some students rush straight to the formula.

They see numbers and immediately start calculating.

But they haven't stopped to ask:

“What is actually happening in this question?”

And that is where the trouble begins.

Imagine a question about a car moving along a road.

Before reaching for a formula, picture the car.

Is it speeding up?
Slowing down?
Moving at constant speed?
How far has it travelled?
How long did it take?

That mental picture helps you decide what information matters and which Physics principle applies.

The same thing happens with forces.

Don't just see “50 N” in a question.

Picture the object.
Picture the force acting on it.
Picture the direction.

Once you can see the Physics in your mind, the mathematics becomes much easier to organize.

Physics is not just about calculating. It is about understanding what is happening before you calculate.

So the next time you get stuck on a Physics question, don't immediately ask:

“Which formula should I use?”

Ask:

“What is happening here?”

Picture it first.

Then solve it.

PHYSICS IS A PUZZLE

One day in the class, a student of mine looked at a Physics question and said:

“Ma, I don’t even know where to start.”

I smiled and asked,
“What if this is not a difficult question… but a puzzle?”

We looked at it again.

First, we found the clues.
Then, we identified what the question was asking.
Next, we picked the right Physics idea.

Suddenly, the same question that looked scary started making sense.

And then came that beautiful moment:

“Ohhh! So that’s what they are asking!” 😄

That is why I tell my students:

Don’t fight a Physics question.
Solve it like a puzzle.

Look for the clues.
Break it into pieces.
Take it one step at a time.

Lesson: Physics becomes easier when you stop seeing questions as threats and start seeing them as puzzles.

What Physics topic has ever made you say, “Where do I even start?” 😂👇

STOP READING PHYSICS LIKE A STORYBOOK.

You can read ten pages of Physics today and still remember almost nothing tomorrow.

Why?

Because reading alone does not mean learning.

Some students sit with their textbooks for hours, moving from one paragraph to another, highlighting definitions and memorizing formulas.

Then the teacher asks:

“Explain what you just read.”

Silence.

Or worse…

They understand the notes but cannot solve a simple question.

Physics is different from reading a novel. You don't just read it—you interact with it.

When you study a topic, ask yourself:

👉 What does this concept mean?
👉 Why does it happen?
👉 Can I explain it in my own words?
👉 Where do I see it in real life?
👉 Can I solve a question about it?

For example, don't just memorize that friction opposes motion.

Look at your shoes when you walk.

Ask yourself: “Why don't my feet simply slide backward?”

Now you're thinking like a Physics student.

The goal is not to finish your textbook. The goal is to understand what you're reading.

Read less passively.
Think more deeply.
Solve more questions.

That's how Physics starts making sense.
