Why Students Struggle With Physics and How to Make It Easier to Understand

Physics can be an exciting subject because it explains many of the things students encounter every day. Motion, energy, forces, electricity, waves and the behaviour of matter can all be described using physical principles. Yet for many students, Physics becomes increasingly difficult as they move through secondary school.

The difficulty is not always a lack of ability. In many cases, students struggle because Physics requires them to bring several skills together at once. They need to understand scientific concepts, interpret information, use Mathematics accurately and apply principles to situations they may not have encountered before.

When one part of that foundation is weak, more advanced topics can quickly become confusing.

Physics Requires More Than Memorising Formulas

One of the most common difficulties students experience is treating Physics as a subject of formulas that simply need to be memorised.

Formulas are certainly important, but knowing that F=maF = ma does not automatically mean a student understands force, mass and acceleration or knows when the relationship should be applied. A strong Physics student needs to understand what the quantities represent, how they relate to one another and how the relationship can be used to analyse a problem.

This becomes particularly important in examination questions, where the information may be presented through a diagram, written scenario, graph or practical situation rather than in the exact format students encountered during revision.

Mathematics and Physics Are Closely Connected

Students who find Mathematics difficult can sometimes experience additional challenges in Physics. Calculations, rearranging equations, working with units, interpreting graphs and handling ratios all appear regularly in Physics.

However, this does not mean a student needs to be exceptionally advanced at Mathematics before they can succeed in Physics. What matters is developing the mathematical skills required for the level of Physics being studied and understanding how those skills apply to physical situations.

For example, a student may be comfortable rearranging an equation in Mathematics but struggle to understand what the variables represent in a Physics problem. Connecting the mathematical operation to the physical meaning is an important part of learning the subject.

Understanding the Principle Comes First

When a student encounters a difficult Physics topic, repeatedly memorising notes may not solve the underlying problem.

A better starting point is to understand the principle.

Consider motion. Rather than simply memorising equations, a student should understand what acceleration represents, how velocity changes and how different quantities are related. Once the underlying idea is clear, the equations become tools for describing and solving problems rather than isolated pieces of information.

The same principle applies to electricity, waves, mechanics, energy and other areas of Physics.

Diagrams Can Make Difficult Ideas Clearer

Physics often becomes easier when students learn to represent a problem visually.

A diagram can show forces acting on an object, the path of a projectile, the arrangement of a circuit or the behaviour of a wave. Drawing the situation can help a student identify the information that matters and decide which physical principles are relevant.

This is especially useful when examination questions contain a lot of written information. Before beginning calculations, students should learn to translate the problem into a form they can reason about.

Students Need to Practise Applying Knowledge

Understanding a concept during a lesson is only the beginning.

Students need opportunities to apply that knowledge to different types of questions. A question may require a straightforward calculation at first, followed by a more complex problem involving several steps or a situation that looks unfamiliar.

This is where guided practice becomes important. Students can learn how to identify the relevant information, select an appropriate approach, carry out the calculation and check whether the answer makes physical sense.

With enough practice, this process becomes more natural.

Mistakes Can Reveal the Real Problem

A wrong answer does not always mean that a student does not understand the topic.

The error might come from an incorrect unit, a mathematical mistake, a misunderstanding of the question or the selection of an inappropriate formula. Identifying the source of the mistake is therefore more useful than simply looking at the correct answer.

A tutor can help students develop the habit of examining their working and asking where their reasoning changed direction. Over time, this can help students recognise recurring errors and become more careful and independent.

Building Confidence Through Clarity

Students can lose confidence in Physics when several difficult topics begin to accumulate. They may start to assume that the subject is simply beyond them.

Often, what they need is not a completely different ability but a clearer route through the material.

Breaking a complex concept into smaller ideas, connecting it to something familiar and then building towards more demanding applications can make the subject feel considerably more manageable. As students begin to solve problems successfully, their confidence can develop alongside their understanding.

Preparing for GCSE and IGCSE Physics

For students preparing for GCSE or IGCSE Physics, effective preparation should combine conceptual understanding with examination practice.

Students need to become familiar with the content of their particular specification, understand the principles behind the topics they study and practise applying those principles through appropriate examination-style questions.

The strongest preparation is therefore not simply about completing as many past papers as possible. It is about understanding why an answer is correct, recognising how questions are constructed and becoming comfortable with applying knowledge in unfamiliar situations.

Making Physics More Manageable

Physics becomes much less intimidating when students understand that they do not have to know the answer immediately. They need to develop a reliable way of approaching the problem.

Read the question carefully. Identify what is known and what needs to be found. Think about the physical principle involved. Use the appropriate mathematical relationship, work through the calculation carefully and consider whether the result makes sense.

These habits take time to develop, but they can transform the way a student approaches Physics.

At Onayemi Academy, Physics tutoring focuses on clear explanations, conceptual understanding, guided problem-solving and progressively challenging questions. Lessons are adapted to the student’s current level and curriculum, helping them develop both subject knowledge and the confidence to apply it independently.
