How to Study Physics

Stop memorizing formulas. It's the biggest mistake students make and the main reason physics feels impossible. You can't just cram equations and hope they stick. They won't.

Physics is about understanding why things work. The formula is useless if you don't get the idea behind it. It’s a tool, and a tool is useless if you don’t know what it’s for. Like having a wrench but not knowing what a bolt is.

Concepts First, Problems Later

Before you even touch a practice problem, you need to get the basic ideas down. Force, energy, momentum, velocity—they aren't just vocabulary words. They're the building blocks. If you jump straight to the problems without understanding what these things are, you're just going to get lost.

Try explaining a concept to someone else. If you can't put it in simple terms, you probably don't get it yourself yet.

I remember trying to get my head around torque. I spent a whole afternoon getting nowhere. It was exactly 4:17 PM, I was staring at my textbook, and my 2011 Honda Civic was parked outside, mocking me with its simple, mechanical existence. I went outside, got the tire iron, and just loosened and tightened the lug nuts. Feeling the force change as I moved my hand further from the nut—that's what made it click. No equation did that. An actual, physical experience did.

How to Work Through a Problem

Once the concepts make sense, you can start doing problems. But don't just start plugging in numbers. Have a system.

1. Read the problem. All of it. Don't skim. Underline the key info.
2. Draw it. Seriously. A quick sketch or a diagram makes everything clearer. It helps you see the forces you're dealing with.
3. List what you know. Write down every given value and what it represents.
4. Figure out what you need to find. What's the actual question?
5. Find the right formula. Now you can pick the equation that connects what you have to what you need.
6. Check your work. Does the answer make sense? Keeping the units in your calculation is a simple way to catch a lot of dumb mistakes.

You Have to Actually Use Your Brain

Just reading your textbook over and over is a waste of time. The information won't stick. You have to force your brain to pull the information out on its own. It's called active recall.

• Flashcards: Don't just flip them. Actually try to answer the question before you look.
• Teach it: Try to explain a concept to a friend. Or just talk it through out loud to yourself.
• Summarize: When you finish a chapter, close the book and write down the main points from memory.

And you need to review things more than once. The best way is to space it out—review something a day later, then three days later, then a week later. It's proven to work better for memory. There are apps for this; they can set up reminders and help you build a habit, which is honestly half the battle.

Do the Hard Problems

It feels good to do the easy questions you know how to solve, but you're not learning anything. The real learning happens when you get to the problems that make you stop and think. Those are the ones that show you what you don't really understand yet.

And when you get a problem wrong, don't just glance at the answer and move on. That's the worst thing you can do. Put the solution away and try the problem again from the beginning until you can solve it yourself. That's how you learn the steps.

It’s all about consistency. A little bit of focused work every day is way better than one long, painful cram session before the test. Block off time to just work on physics. No phone. No distractions.
