So, you want to get good at physics?

There's one thing that separates people who excel at physics from those who constantly struggle.

And it's not about spending more hours studying, having a better teacher, or being naturally gifted at science.

It's about knowing what actually works.

In this video, I'll walk you through six steps that will completely change how you learn physics.

Whether you're starting from scratch or aiming for high grades.

Don't skip around because these steps only work when you use them together.

Master the core concepts.

One of the biggest mistakes when learning physics is treating it like a memorization contest.

You try to cram as many formulas as possible into your head, but a few weeks later, those formulas are completely gone.

This approach doesn't work because it misses the most important part: truly understanding what the formulas mean.

Physics is a system of interconnected ideas that explain how the universe works.

Every equation tells a story about the physical world.

Take Newton's second life law.

It's telling you that every time something accelerates, there's a force causing it.

When you kick a ball and it starts moving, when a car speeds up from a red light, when a rocket launches into the sky.

This principle is at work.

To really own this, it is useful to study the derivation of the main formulas.

When you only see the final formula, you know how to use it, but not why it works.

Studying the derivation shows you the logical steps Most students memorize it as a separate formula,

but it's not.

If you start with Newton's second law and the definition of work, you can derive kinetic energy step by step.

What you discover is that kinetic energy isn't something separate from force and work, but actually comes from the work done by a force to accelerate an object.

So, this shows you that force, work, and energy describe the same physical reality from different perspectives.

a force, doing work because you're moving it, and transferring energy, which becomes the car's kinetic energy.

This kind of understanding lets you solve problems in different ways.

If we take this problem, once you understand the derivation of kinetic energy, you realize you can solve it using either forces or energy,

because you know they lead to the same result.

Some problems are extremely complicated with forces but trivial with energy, while others are the opposite.

When you choose the simplest method for each problem.

Step 2: Ask yourself questions.

One of the most effective ways to truly deepen your understanding is to ask yourself questions while you study.

When you encounter a physical law, actively challenge it.

Let's take Ohm's first law for electrical circuits as an example, where V stands for voltage, I for current, and R for resistance.

Instead of just memorizing it, start asking questions.

What happens if resistance is zero?

In this case, even a small voltage can create a short circuit.

What if resistance were infinite?

This means you're dealing with an open circuit where no current flows.

Where do you see this daily?

You can notice this law in your phone charger, which heats up because the current flowing through its internal resistance, produces heat.

You also see it in lightning, which occurs when an enormous voltage overcomes the high resistance of the air and a visible current is created.

These questions help you connect the formula to what you see in everyday life, building a deep understanding of the that goes way beyond surface level memorization.

Step 3: Study physics the right way.

Understanding the concepts is only half the work.

The other half is how you actually study.

You can spend hours with your books, but if you use the wrong approach, the concepts will never click.

The difference between those who struggle and those who get good grades isn't intelligence, it's method.

So let's look at some practical strategies that will help you study smarter.

Create a personalized study routine.

Studying Getting without a plan is like doing the wrong workout at the gym.

You're putting in effort, but you're not getting the results you want.

You need a structured routine that adapts to your life and your rhythm.

Start by identifying the times of day when you have the most mental energy, maybe in the morning or afternoon after classes.

You don't need 5 hour marathons, even 45 to 60 minutes of focused study every day produces excellent results.

Within each session, alternate between theory and practice.

concepts, then use the remaining time -solving problems by applying what you just studied.

At the end of the week, do a general review of the topics covered and identify what's still unclear so you can focus on that the following week.

fields, you can't tackle Maxwell's equations, which include it as a foundation for explaining electromagnetism and light waves.

So, if you realize you're lost, take a couple of days to review that specific chapter, watch a YouTube video explaining that concept,

or redo the basic exercises.

It's much easier to fill a gap immediately than to reach mid -semester

and discover you don't understand anything anymore because you were missing a definition from the

stick is to connect it to a concrete image.

Your brain remembers things it sees much better than formulas written on paper.

That's why you should actively seek out visual material while studying.

Just avoid learning physics from cartoons, because, you know, unfortunately, that's not how physics actually works.

You can watch YouTube videos showing real experiments.

Infographics are great for visualizing complex processes in a simple way.

Or use interactive 3D models that help you structures work from every angle.

Learn to recognize the most common mistakes.

Many students lose points not because they don't understand physics, but because they keep falling into the same avoidable mistakes.

Recognizing them in advance is the first step to stop repeating them.

The most common errors typically come from three main reasons.

Misreading questions, neglecting units of measurement, and making mathematical mistakes.

To avoid them, every time you get an made and why you made it.

This way, you'll recognize recurring patterns and know exactly where to focus your attention to avoid them next time.

Use practical physics tests to prepare for real exams.

Beyond the exercises in your textbook, you can use additional problem sets you find online on sites like OpenStax and Khan Academy.

For free resources with more advanced problems, I recommend this workbook that offers an extensive collection of problems,

compiled from College Board Physics Bowl competitions.

There's also a book called "1000 Solved Problems in Modern Physics" which covers advanced topics including thermodynamics,

solid state physics, and more.

You can also work through official past exams from previous years, which will help you understand what types of problems you're most likely to encounter.

Step 4: Learn the math skills to solve problems.

If you really want to improve in physics, you need to work on the math too.

physics concepts become hard obstacles to overcome, whether it's algebra for solving equations, trigonometry for working with angles,

or calculus for analyzing continuous changes.

Each mathematical tool gives you a systematic way to approach physical problems.

The more fluent you become with these methods, the faster you can set up the problem correctly.

Step 5: Solve a lot of problems.

Doing lots of exercises is the only way to truly master physics.

method.

To see how to apply this method, imagine this problem.

This is a classic physics problem where the typical goal is to determine whether the block slides

and calculate its acceleration along the plane.

The first thing to do is understand what the problem is telling you, and identify the known data and unknowns.

You know the block's weight, the initial velocity, the plane's angle, the coefficient of dynamic friction,

and there's a distance of two feet gives you the block's weight in pounds, not its mass.

100

Weight and mass are two different physical concepts that are often confused.

101

Weight is the gravitational force acting on an object, and changes if you're on Earth,

102

the Moon, or Mars, while mass represents the amount of matter contained in that object, and always remains the same regardless of where you are.

103

In the imperial system, weight is measured in pounds, while mass is measured in slugs.

104

To use Newton's second law, by dividing by gravitational acceleration.

105

In the imperial system, this equals 32 .2 feet per second squared, so the mass is 2 divided by 32 .2,

106

which equals about 0 .062 slugs.

107

At this point, move to the planning phase.

108

This is a dynamics problem on an inclined plane, so you'll need to break down the weight into components parallel and perpendicular to the plane,

109

calculate the normal force, determine the weight to see if they're sliding,

110

and finally apply Newton's second law to find the acceleration.

111

The third phase is executing the calculations following the plan you've established.

112

In our example, performing the calculations gives us an acceleration of about 10 .5 feet per second squared.

113

Before moving to the last step, take time to analyze the solution and ask yourself if it makes sense.

114

An acceleration of 10 .5 feet per second squared is about one -third

115

reasonable for a block descending on a 30 degree inclined plane with friction.

116

If the angle were steeper or the friction lower, the acceleration would be greater.

117

If the friction were higher, the block might remain stuck.

118

This type of final analysis trains you not to see the problem as a sequence of mechanical calculations, but as a real physical situation that you can deeply understand.

119

When you're confident in the result, you can move on to check if the answer is correct.

120

Step 6: Technical intuition is the ability to understand how phenomena work, even before performing calculations.

121

It's important because it allows you to recognize recurring patterns in problems, and when you face new ones,

122

intuition helps you connect them to similar situations you've already solved.

123

Think of it like chess.

124

A beginner must calculate every move from scratch, while an experienced player immediately recognizes piece configurations they've seen before,

125

and instinctively knows which are the best moves.

126

an immediate skill, but it develops over time.

127

The good news is that it can be trained.

128

To develop it, expose yourself to a wide variety of problems and different physical situations.

129

For example, if you're learning the momentum conservation principle, you should explore very different scenarios like elastic collisions where objects bounce,

130

angled collisions, situations where a moving object hits a stationary object, collisions with very different masses.

131

The more diverse similarities.

132

If you combine this intuition with a solid mathematical foundation, you become practically unstoppable.
